I like free games. I like driving/racing games. Put them together and you have TrackMania Nations Forever which is available for free from Steam.
This post is the first in a series of TrackMania Nations Forever videos and since each section (White, Green, Blue etc races) contains 15 tracks, the posts will be broken up into 5 videos each. I probably could have just put them all together in one continuous video, but kept them separate mainly for reference of each track.
You can buy TrackMania United Forever from amazon for slightly less than it is on Steam and features a whole lot more than the Nations version. It’s also available for the DS at just £6.24 (at time of posting and including P&P) with a version coming soon to the Wii.
