I recently purchased the anniversary Command & Conquer pack, which has all 15 C&C games on one DVD!
There were A LOT of problems with the install, such as certain games just not playing due to corrupt files, and the networking not functioning on VISTA. Most of these I discovered are common problems with the release an managed to find user workarounds online.
I find it amazing that titles such as C&C (the original) and Red Alert 1 are timeless. Sure the graphics are a little dated, but the gameplay elements are still as slick and enjoyable as they were 10 years ago.
Even the C&C Red Alert trailer is still cool!
I think I may have to get round to checking out RA3 soon!
