This, I think, is a top sign that you should play more games.
Examples?
I start a lot of games, but very few of them manage to capture my attention these days. Arkham Asylum had it all - story, characters, learning curve, gameplay, graphics, music, and voice acting. The few minor qualms I had about the game were so insignificant compared to the game's merits that they are barely worth mentioning.
See, that's the funny thing. Over the past ten years there are three games that I've started, but haven't been sucked in enough to finish. They are: Call of Cthulhu: Dark Corners of the Earth, GTA IV and Arkham Asylum. I have to admit, while I know what my beef with the first two games of the list are, I'm having a lot more trouble putting my finger on it with AA. For some reason, whenever I boot it up, I just become really, really bored very quickly. Guess it just shows how people are different. I adore Mass Effect 2, and I believe a lot of people here have similar issues with it that I have with AA. *shrug*
