What kind of temps are we talking about to not let you sleep? And can't you do something about it, like getting an AC unit (even a portable one)?
As for being burned by games, it happens to most, if not all, of us every now and then. What I use to do is try to find a game I could like from a genre I don't use to play. I usually end up either liking the game and wanting to try more game like that, or hating it and appreciating a lot more the other games I use to play, giving me a reason to play them again.
Please excuse my bad English.
