There are other mmorpgs out there that differ from wow far more then rift does. I played this one game that came out before wow and is still somewhat alive. I eventually had enough of it because to stole too much stuff from wow and if i wanted to play WoW, i'd play WoW. We had instances and Battlegrounds. But this game was scifi, so the battlegrounds where Battlestations. Innovative.
And there was the grind. Which i don't like all that much, but it is found in pretty much every mmorpg. After seven years of mmogrind, i've had enough to last a lifetime.
In the meantime, i played "oblivion" which thankfully rescued me from mmorpg grinding.
No People who will constantly search for some loophole in the game mechanics with the sole aim to ruin your experience. I liked the community in my game, but you'll find these people everywhere. Well, in single player games you don't.
You also wont level backwards. Sure, mmos will have your numbers climb up, but in comparison to the creatures you fight, you get weaker and weaker until you reach a point where can do nothing alone. Maybe this character was a twink once, made for the levelscaled midlevel instance which he then cleared out himself. When he raises in levels, the character wont be able to do that again. The character will need help of a team. Later, that team will have consist of certain characterclasses.
In the endgame, only good teams with a fast TC (Target Caller), a good RL (Raid leader) and tanks with maximized taunts to keep aggro from the DDs (Damage Dealer) and the healers will get anything done.
I'd be surprised if Rift didn't do this.
Single player games wont. I was surprised how fast my XP bar was climbing. I get this good piece of armor without having to teamgrind hard as rock bosses who drop items that i then have to craft into something that can teleport me into an instance where i have to defeat a boss which drops something that i have to craft into my new shiny armor?
In singleplayer games, you can find loopholes that could totally break your game. And you don't have to report them to some GM and then get banned because he thought you where using that loophole. How could you have found it otherwise?
Well, my mmorpg days are over. Good Riddance i say.
