Steam achievements are the EXACT FUCKING SAME as the 360/PS3 ones.
No they're not... they're terrible
- not every game has them (HUGE issue), while every single 360 game and even XBLA games have them
- there's no cumulative score so nobody gives a shit
- you can't easily see your friends scores.. because 1.) they don't have scores and 2.) they're hidden inside the community tab that people rarely visit. Compare this to Xbox Live and how achievements are front row and center... from the friends blade to the mini dashboard, to the top right of the damn screen. You can so easily compare your achievements with your friends.. it's encouraged
Steam achievements are worse than Trophies.. they're half-assed and just terrible
Shut up you elitist PC scumbag
