Quite frankly, I am in love with Supreme Commander...and practically any RTS games I played as a kid...that includes Red Alert, Tiberian Sun (best in-game atmosphere ever!
), Red Alert 2, and all the expansion packs for the three of them...games I also expect to purchase are: Spore, Sins Of A Solar Empire (like SupCom except in space; looks awesome, by the way), Half Life 2 Episode 2/Portal, and
maybe CnC 3...oh, and of course, I have already purchased Overture...if it lives up to the Penumbra Tech Demo, and I can get the bloody authentication code to work, then it will soon officially be on my list.
The two screenshots below are from Sins Of A Solar Empire.
