Attention Achievement whores

Have you ever thought to yourself "Do I want to put this game in my machine?" Either you think you wont like it or you wont have time to complete it and you don't want the achievement points on your tag. Am i the only one who thinks this. I put Def Jam in and now its on my gamertag. It's quite shitty. I didn't play Lostworld because of this. Maybe I'm just weird? I don't know but I do know I hate it when I get a game and only get a couple points! Does it matter to you? Let me know.
