This is a pretty old game (by gaming standards), but it is a fun one. As it's older, it can play on most computers - just check your specs just to make sure.
I have all the expansions... and if you do get them all into one computer, it's a pretty buggy game. However, if you're just playing the base game with 1 or 2 expansions, it runs well and there is still lots to do and play around with.
The 3 for 1 deal is the best value I've found as well. Makes a great gift for teens or people who wants a little casual gaming.
