Sure. I can help you. Both Wine and WineBottler, or Wineskin Winery will let you create virtual machines to run Windows Games in. Wine is more complex to use, and involves typing in a lot of arcane commands which I don't know how to do, so i go with WineBottler or wineskin winery. Both are a little easier to use, and they do work for some things, but you may have to tinker under the hood to get some games working. Also bear in mind that the Wine bottle will not really use the graphics card built into your MacBook, and the game will have certain basic requirements that you must meet before you can hope to play it. I've also heard that CrossOver Mac works fine, but it's not free. It is, however, not too painful to use. I'm guessing you don't want to spend a ton of money to play Windows games, right? also check out portingteam.org (could be portingteam.com_ to see if someone has made a Mac port of that particular Windows game. Oh and one last thing. Older games, say from 2007 or earlier stand a better chance of working than do more modern games. If it says Direct X 9 somwhere along the line, you should be okay. There are also forums at the winebottler site and wineskin winery site, maybe even at the wine website so if you're stuck on how to use it, and how to do certain things, or even if you can do certain things, or you can't, they'd be the one to ask.
