Welcome Shaefer to the community! I'm glad to have an Aspyr rep to participate in our forums. Glad someone pointed out a lot of people in here speak English as a second language, so just keep that in mind if you read something that sounds overly critical or wrong. I've been in these forums casually for several years now, and I have to say the Civ Mac players are quite friendly
I've bought every game of Civ since Civ 1 on my old Commodore Amiga computer, then PC versions, and Mac versions. Overall, it seemed like Aspyr's port of Civ 4 was released sooner after PC release than the previous company's port of Civ 3, and Aspyr's re-porting of Civ3 was more stable. BUT, I sure would like releases sooner and patches/fixes more frequently. There's nothing worse than having known bugs left unfixed/patched for long periods of time.
I have no idea what relations are like between Aspyr and Firaxis, but it would be awesome if Aspyr could participate in or have some sort of liaison with Firaxis during Civ 5 development to help tweak things along the way to make it port easier in the future.
