It's happened to me quite a few times, and I was wondering if I'm the only one who has suffered it?
Game Genre Overload is what I call when you play too many games in the same genre and all of the sudden you just can't play that genre for a while...
The first time I remember this happening to me was when I tried to beat all those adventure games I've never beaten... I almost hated adventure games after that ordeal and couldn't enjoy them again until Telltale game around!
The latest case is RPG overlord, which happened to me after playing the extra awesome Lost Odyssey, and after that it seemed that all I had was RPGs!
But I noticed that it's not only playing games of the same genre which cause this, I'm beginning to think the biggest factor is the quality of the game, when you get Game Genre Overload you get very nitpicky and you end up disliking games you'd probably wouldn't complain about if you weren't "overloaded"...
During this RPG Overload I discovered I never liked SRPGs to begin with and once I gave up on Enchanted arms and moved onto Blue Dragon I felt much better, I could probably even play Fallout 3 or Fable 2 now even!
Does this make it a blessing or a curse? On one side I'm quiting games I probably would have forced myself to finish otherwise, but am I giving up on a game that I'd enjoy if I weren't overloaded?
