Might and Magic X Legacy (Forthcoming; 2013]
I loved the early M&Ms, the Xeen series.
I enjoyed the 3D M&Ms VI VII VIII. The 3DO engine rendering was acceptable for that time standards.
M&M IX is a rip off, the gameplay is so bad, I found it impossible to play.
I wonder about X legacy, and it's computer requirements.
