Even if you can find a copy of Chess Titans and you installed it in Windows 8 you would be breaking the terms of your Windows 8 release. As stated elsewhere there are chess games in the store, Also there is MSN games witch I use, and several are available
from the Internet.
I feel the best way to enjoy these games though if you have a full version of XP, Vista or Windows 7 and it is not being used I would a software such as Virtual Box, Hyper-V and in stall your operating System in Virtual mode. That way you can have legal
access to you r Chess Titans.
Hope this helps and if you need further assistance post and we will be glad to Help you.
