Personally I'm a fan of AppleStore UK. I've bought PC games from Amazon before now, and although they despatch the same day, they send stuff by VERY slow snail mail that can take a week to arrive. Apple, although they despatch "within 68 days" are actually MUCH faster as they use courier services, so I have received everything I've ordered from them 23 days after placing my order.
I used to use Amazon for all my Mac games, however I rarely play games on my G5 now. I am not sure of you play multiplayer games online but thats all I will play namely Moh:AA however there is a lack of Voice Communication software available for the Macintosh platform, namely the two top ones Teamspeak and Ventrilo.
Back in the day Roger Wilco used to be available, however the program was very dated and only ran in Classic. I will be more than happy to go back to the Mac for gaming when this becomes available + decent Anticheat such as DMW scanner.
I am not sure of you like Ravensheild but if you mail me I have a copy here thats just gathering dust.
Ain't that just the awful truth! As a Mac online gamer MoH Spearhead & Call of Duty it's SO frustrating not being able to communicate with the rest of the clan. Currently investigating Skype, but it's a nightmare trying to get all the PC wallahs in {**9**}*TheNiners* to switch.
Personally, I'd go for MacGold. They usually have some really good prices, along with free first class delivery to the UK. And they've never given me any hassle in the years that I've been using them.
