It's the trendy thing right now to claim that Achievements are worthless and stupid, but according to Microsoft, such sneering hardcore gamers are in the minority. According to Stephen Toulouse, Achievements are a proven game seller.
"It's been statistically shown that games that have Achievements and implement them well sell better," Toulouse told Major Nelson in a recent podcast. Naturally, Toulouse did not provide any of this statistical information, but he said it so it must be true.
Sarcasm aside, I can believe this. While Achievements hold no significant value, I must admit that I find the unlocking of them rather fun, moreso than I do Trophies on the PS3. If a third party game is available for both the 360 and PS3, I'm going to go with the 360 version just because the Achievements add that tiny bit extra. I know there are plenty of others with the same mentality.
Do Achievements influence your own purchasing decisions, or do they hold no sway over your mind whatsoever? You can admit you're disgusting a Cheevo Whore, we're all friends here.
