I am usually very generous with giving time to a game I eventually stop playing. Granted, I've very picky about what games I pick up so I'll usually stick to a game cause there was something about it that intrigued me to begin with. I'll even finish a game if I don't like it if I learn I'm not far from the end such as FFXIII or Revenant Wings.

I'm usually nicer to games than TV. I sometimes will drop a show mid-pilot episode if I get bored. Games have the luxury of having multiple ways of entrapping me such as the plot and the gameplay and if one of those elements is strong enough, I can usually see myself to the end unless the other element is truly atrocious. The only two games I've abandoned recently on purpose and not simply because I got distracted by something more shiny have been Drakengard and FFX-2.

Drakengard has some interesting characters and narrative, but the gameplay is abysmal and unfortunately taps into my OCD in ways that make it even worse for me. I would like to think I will finish it someday, but it will likely be awhile. I did get about a third of the way through before I called it quits.

X-2 is just... ugh. I honestly can't fathom what people see in this game. Even the much hailed combat isn't really that great, and the story is just painful to watch. I was running around my second or third dungeon before I convinced myself that there had to be some other game in my backlog that I could slog through that would be better and sure enough there was. I faintly remember that it took me two years or so to finish my original playthrough of the game.
