I feel old, although I am 18. I get bored easily of the newer games because its the same concept, only with better graphics and sound. Same controls: move, jump, kill baddies, solve puzzles. Nothing new.
When something innovative comes along, I feel young again, like when I first played Sonic or my first fighting game. But then some big-wig company buys them out and the sequel sucks and the innovation dies.
I also feel like some games could have been longer, like God of War or Kingdom Hearts. Yes the action was repetitive and some puzzles you wish to never do again. But they were great games, and I was disappointed when it ended so suddenly. Some games should be shorter (Oblivion, Morrowind, WoW) because when theres so much to do, you feel overwhelmed and you give up because you think "I will never get all this done".
To sum it up, really, I wish kids these days weren't sucked in to buying cheap games with horrible story lines and even worse characters. The original Sonic, Mario, Spyro, and others were great characters. Nowadays, Sonic is some punk rocker, Spyro is out to save the rainforest with his forest friends, and my 6 year old cousin didn't even know about SMB64. That both saddens me and makes me feel like an old man.
