What Game do I own? Very good question, but I'm don't really know.
I have 2 selves full of game boxes, but I actually can't remember what most of them are, most just don't keep my attention to long.
I have only bought both SE IV Versions (other then kids games & some Castle building game that my wife gave me) in the longest time.
Only ones I actually have installed are:-
Space Empire IV & IV Gold.
MechCommander Gold - My 3.5 year old son loves this. He can't read yet, but knows every mission and objective from the mission map. I expect that he will be better then me a another year
Red Alert - Firestorm - My son has just found this game, I didn't even realise I still had it installed
Fate, Gates of Dawn (Amiga game) - Love this one, and just revived it using an emulator.
Commandos
Ultima 1-8 boxed set.
Jagged Alliance
