Several PC Games in their bargain section INSTORE at the branch in Cambridge. (Bargain section at rear end of the store.)
Supreme Commander: 99p
Titan Quest (Not including the expansion pack): £1.99
I do not know the exact price, but they are going for cheap (£3 at the most):
Prince of Persia(s)
Splinter Cell (Sorry not sure which one)
Medieval Total War (2 perhaps)
Power Rangers Ninja Storm
There are more games, but I don't have an amazing memory...
Many of these are 'Focus Essential' branded games. Supreme Commander and Titan Quest are both excellent games and are definately a bargain (if you have a pc that can run both) for the prices mentioned. I am not sure if these kind of prices will be found across the country. Titan Quest is going cheaper than that found on Steam.
First post so I hope I have sufficient details. I've searched for PC World deals and have not seen this posted already.
