Gameboy Advance Games

[Arehexes]

To many to name (Note I collect games in series to "complete them")*deep breath*
Sonic Advance Series (including Battle)
Megaman Battle Network series (I loved 2 and 6 the most)
Pokemon Series (But I prefer Emerald over the rest)
The Fire Emblem Games(Yes even the JP only game)
Mother 3
Advance Wars 1 and 2
The Final Fantasy Advance remakes (I love 5 and 6 the most)
Metroid Zero Mission
Golden Sun 1 and 2

 

[Shock and Awe]

Fire Emblem: Sacred Stones and Metroid: Zero Mission are among the finest games ever created.

 

[SH4DOWSL4Y3R]

I'd have to say these would be some of the best for me, a lot of them have been aforementioned if not all.

Final fantasy I+II dawn of souls (first game i ever owned for gba )
the legacy of goku games(including buu's fury)
Metroid fusion
the Golden sun series
The pokemon series

There were others but these are the most prominent.

Call me a weirdo but I loved the Mario Tennis game for the GBA.

Me too, friend. GBC one was better though.

Never played that one... did it have the same RPGish feel?

I'd vote for Megaman Zero. Some of the best hack-and-slash platforming I've had the pleasure of enjoying.

I played so much River City Ransom: EX back in the day. Since I never had a Super Nintendo, I also played a lot of Yoshi's Island and Super Mario Advance on my GBA.

Honestly it was essentially the same game but without power shots.

Not weird at all. The golf game (Advanced Tour I think) was also good.
I loved the RPG elements.

in order to truly complete the megaman battle network series, does that mean you got "Megaman: Network Transmission" for Gamecube? it was supposedely inbetween two of the GBA games and it completely rocked (if a little steep on the difficulty side at first, but you adjusted)
I never had any luck finding the other megaman games in the gamestores

anyway, i agree with every poster so far...and would like to add "Kirby: Nightmare in Dreamland" to the mix

Star Wars II was also quite good, if somewhat very easy, it contained much fun and re-play value.

Tales of Phantasia got about 40 hours sunk into it. until all my save files corrupted for absolutely no reason and i lost my high level characters, advanced summons and everything else in the game.

Same happened with harvest moon: friends of mineral town, i must have easily played just as many hours of that, only for the save files to stop working...but i didn't get anywhere near as angry about it

Spyro Adventure (or Attack of the Rhynocs as I think it's called in the US). Amazing game.

 

[Durananrananrananran]

Along with Golden Sun, and Minish Cap, I want to second Astro Boy - would be good to see a lets play of that game.

Any of the Marios, although pretty straight ports, are all good, obviously
