It's kind of funny, while a demo of Combat Mission Africa Korp has give me enough to piddle with game wise, it's kept me from really wanting to shell out the $35 for the full product. It's so simular to the others, I really hate paying for the same thing over again, even though I like this area of conflict, but, I have a mod for Combat Mission Beyond Overlord that does the desert warfare.
On the other hand a demo of Strategic Command was enough to sell me on the rest of the game, I still haven't bought it yet.
I haven't beat EYSA demo yet either, so before I want the full version I have to be able to beat the demo! lol
A demo can keep a person content with the game without having to have the full product, I have Doom origional demo that I found to be plenty of shootemup for me without purchasing the whole game. Same with Heretic and a couple of other shooter demos.
Demo or not though a game really has to be something majorly special and NEW, not just a copy or repeat of something that has been done to death like RTS games. I have Age of Empires full edition, but, have only DEMOS of the rest of the blurb that has been coming out over the years since AOE. heh
If anything the Virtual Tour of HTTR showed me it's complexity. It reminded me a lot of a russian front game I have from SSI. While I know a lot of grogs enjoy complex games, over the years I have fallen away from those and prefer more of a beer and pretzels afternoon of gaming, instead of a career of it.

All those stats, right down to the last piece of ammo....headache!

Whatever happened to good ole fashioned Atk/Def/Mv units of the old days?

If I wanted to be a quarter master I would have joined the army.

The game looks great, nice colorful maps, double type icons. Probably a grog who loves complexity dream game.
