1. Metal Gear (The MSX one, not the NES one)
Metal gear really deserves a remake, since 1)There are a few kinks they could fix (room-locked radio calls, guards who only see in a straight line about 3 pixels thick, etc.) 2)It would be awesome in current generation graphics, and 3)It's very difficult to access at the time. (The original is probably long gone, the NES version is crap, ROMs may conflict with your morals and/or laws, some ROMs may not even work properly, and MGS3: Subsistence WITH the second disc is pretty much impossible to find. Trust me, I spent MONTHS trying to track down a copy at GameStop, and finally found a location that had one. And only one.)
2. Metal Gear 2: Solid Snake
This on is even more deserving of a remake, since the only time it was released in the US was with MGS3: Subsistence's Disc 2 (which, as I said before, is a pain in the @$$ to find). It's a shame too, because it was a much more solid game than the first one was. It was about as functional as MGS1, except in 2D. Think of it as the big brother of the Game Boy Color version of MGS. (I believe it was unofficially titled Ghost Babel?) Except Metal Gear 2 had more buttons, so you didn't have to put up with that Select+Directionall Button/Start crap to access your equipment and radio.
2.5 Ghost Babel Storyline
On a somewhat unrelated note, once the MGS timeline is dried up and they can't make anymore (decent) additions to it, they should go back to Ghost Babel and continue it's storyline. For instance, the second installment could feature an airborne, birdlike Metal Gear called Metal Gear ROC. (Roc= "a legendary bird of great size and strength believed to inhabit the Indian ocean area," according to Webster's Ninth New Colegiate Dictionary, just in case you weren't already aware of that.) They could also feature Raiden or some other character as a super badass ninja, possibly a techno one if they really wanted to. (Maybe it could even be Gray Fox, since they left him out of Ghost Babel.) They could also try (and I mean try, cause it would be a pain) to make it rated "E," rendering the Ghost Babel timeline a sort of "Metal Gear Lite" for younger audiences.
3.Pokemon Yellow
Honestly, I'm surprised they skipped out on this one when they made Fire Red and Leaf Green. It would make sense if they were waiting for the DS so that they could take advantage of the technology, but I haven't seen any idication as to that, either. Yellow was a fun game, and it would benefit from a remake. They could 1)Improve it to the modern Bag system, wich is much more efficient, 2)Fix the issue where having two Pikachus (one probably traded from a friend) in the same party crashes your save file, probably by making your starting Pikachu a special one, akin to "Shiny" pokemen, and 3)Take the little feature with Pikachu's feelings even farther, maybe by making the bottom screen a sort of mini pet Pikachu thing.
4.Pokemon Crystal
Ok, I know that Heart Gold and Soul Silver haven't even been released in the US yet, but I have a sinking suspicion that they'll skip over Crystal like they skipped over Yellow. They should make Crystal, because 1)The Suicune side-plot made it a bit more interesting, 2)I personally favor the female character from Crystal over the one from Heart Gold/Soul Silver. At least give us the option to choose which design we want. (And maybe add a new one for the male character to balance things out.), 3)The apricorn trees were limited to 1 per type in the original, with 3 of them being hidden in a semi-secret location. Getting a bunch of special Pokeballs took patience, but it was worth the wait. Now, Heart Gold and Soul Silver are apperently going to have a whole bunch of apricorn trees, which just ruins it, making them too easy to obtain. The remake of Crystal could keep the original number.
5.DO NOT REMAKE FFVII!
Now, don't get me wrong, I loved FFVII. Unfortunately, some of the things I loved about it would be hard to bring over to current generation consoles (strange as that may sound.) For instance, I was fond of Barret's odd charm in the way he blatantly spewed random symbols (representing the foulest of language) with reckless abandon. A remake would entail voice-acting, meaning that the game would be rated M (or even AO), or that Barret would be toned down, stripping him of some of his personality. Also, in the heartwrenching scene where Sephiroth stabs Aeris (or Aerith, damned translation issues) cleanly through the chest, there was no blood. They could get away with it at the time, because of the PS1's limits. Now, however, they would have no excuse, and would have to include blood, which there would probably be a lot of. So, that would also push the game closer to being rated M, which would piss a lot of people off. There are probably many more things that would be changed or removed, but I've typed long enough as it is.
Oh, and someone suggested something about a Kingdom Hearts based battle system in FFVII? That would be a bad idea. Kingdom Hearts is a platformer, with jumping, gliding, etcetera, so the free-roaming battle system works. But Final Fantasy VII is drastically different, and having Kh's battle system put in would either be horribly awkward, or would entail a drastic, complete redesign of the entire game world. So, to that idea, I have two simple words: HELL NO.
EDIT:6.Final Fantasy Crystal Chronicles
The first one was astounding. The portable sequels were ambitious, but not as great. (Also, the Selkies lost their massave boobage, which I'm sure pissed off more people than me.) So, take the original, and port it to the PSP. The PSP has better graphics than the DS, and since each player would have their own, they thus have their own screen, rendering the private GBA menu screen gimmick unneeded. If you still wanted the ability to pause but still see what was going on, or wanted to see the bonus map or treasure radar that the GBA gimmick allowed, just relegate one section of the screen (probably off to the side) to the duty of a mini-menu and radar when not viewing said menu. The PSP has a wide screen, so that wouldn't be too much of a loss.
