I liked the GTA games for about a day. After that it got old. Most people I know got addicted to it for some length of time or another, but a few of my gamer friends didnt like it either. I guess it is more of a matter of gamer taste. Some people dislike FPS games and others dislike RP games.
I like most game genre's but tire of certain ones more quickly than others. It's all about replayability for me.
