One of the complaints commonly leveled against PC gaming is that because of it's open-platform nature, it can feel like a gamble if a game you bought will actually work, especially if you're a novice user. Steam has simplified the process of installing and running a game but it's still not a perfect process.
Step in the PC Gaming Wiki 2.0, which aims to make the biggest collection of PC tweaks, tips, and hardware guides on the Internet. Covering topics like save-game location, workarounds, patching, optimization, and hacks, this wiki looks like it could be the one place to always refer to for any PC gaming needs.
I know I for one will be glad to not have to search through numerous forums and articles looking for a particular bug fix. Having all that info in one place seems like a great idea and I'll look forward to seeing the PC Gaming Wiki grow.
