I haven't used Parallels, but it used to come for free with a new Mac. I don't use VMware (I like the free stuff), but I've heard good things about it. This one is somewhat confusing to download I think you have to compile the emulator by hand. As with anything Apple-related, it should be pretty straightforward. I haven't actually installed it on a Mac, I've used a friend's computer, so I can't help you with installation. I would recommend Boot Camp for 3D stuff. Boot Camp (Free) - Comes with all Intel Macs It allows multiple operating systems to run on your computer. Virtualbox is not quite as lightweight as Q. It supports emulating x86, x86-64bit, PPC PowerMac, PPC PREP, SPARC32, MIPS, and ARM processors. Oddly enough, it runs on PPC Macs, in addition to Intel Macs. Q is a great lightweight CPU emulator for OS X. Old stable and beta releases for Windows, Linux and Mac including plugins. Professionally supported enhancement of Wine Q (Free) Wine (and Crossover) do not require an actual copy of Windows installed on your machine. I would recommend Winebottler, a free binary installer that also allows you to turn a Windows executable into a simple application that launches in X11. You do need to install the Developer Tools, included on your computer's install disc. I would also not recommend compiling it yourself. Run multiple instances at the same time to play. Open keyboard mapping only with one-click, get the real PC like gaming experience by setting the controls on keyboard, mouse, or gamepad. Every feature is perfect for your gaming experience only. I don't know how well it works with 3D stuff. Supports keyboard, gamepad, script recording and multiple instances. I highly recommend Wine, which allows for running Windows applications without actually emulating the whole Windows OS. When using the term 'emulator', it is important to distinguish between something that acts like Windows to applications (like Wine/Crossover) and something that acts like a PC to Windows (most of the other solutions) so that Windows can be installed.
