First time poster, after having lurked on MR for many, many years. I've searched for the following, but haven't been able to come up a really good, clear, answer to my overall questions. Hardware-wise, let's assume we're talking about a new, baseline, 15" MBP with 2.4 GHz Core i5, GeForce GT 330M, 4Gb of RAM (although I'd max this out ASAP - what's the current limit, 8 Gb?). I absolutely do NOT want to consider Boot Camp (I know all about it and have weighed the pros/cons for myself) and suggestions to find Mac versions of any of the games wouldn't be too helpful, in part due to the incompatibility of lots of the Mods available. I'll be forced to use 32-bit Windows XP Pro (with SP3) in the virtualized environment for work-related reasons and don't really want to take up HD space with multiple virtual machines - but I may consider it, depending on the case. First - what would be the ideal amount of RAM & CPU cores to allocate to the XP virtual machine (I'm thinking 1 core, 1 Gb of RAM). That being said, I'd like to know anyone's experiences running the following games in virtual machines (Parallels or Fusion - and it would really help if you specify what you're using, i.e., Parallels or Fusion): Arcanum, Chessmaster XI - The Art of Learning, Freelancer, or Morrowind. I'm already assuming other games I have: Infinity Engine games (Baldur's Gate I/II, Planescape Torment), Diablo 2, Fallout I/II, and other various (read OLD) games should be fine in the XP virtual machine - please correct my assumptions, if mistaken! I appreciate any and all responses - Thanks!
