This is probably about as far from Unreal Tourney 3 as you can get, but whilst tidying my office, I found this little 9-year old gem.
It's mostly a turn based combat game, but during the other players turn, you can do material management and construction at your base, so you can't just sit around forever during your turn, since the enemy are doing the same thing, so the game-flow works quite well.
If you haven't played Battle Isle before, it's kind of hard to describe, the originals were brilliant turn-based strategies, with loads of weapons, from the missile-buggy, scourge of the early stages, to rail-mounted artillery to the Behemoth super-tank, and a damn smart AI, the one main advantage of turn-based games.
TAW follows most of the original concepts, but is 3D instead of 2D like previous versions. My only concern about it is that, like many games of this type, it seems to have lost a degree of diversity of units by going 3D. Same thing happens with city-builders like Ceaser IV, for example. Though, in all fairness, I'm still pretty early in the campaign, so I may be wrong, I'm just going from the manual that came with the game.
If you're an adrenaline freak, forget it, this game will barely raise your blood pressure apart from when you watch your most skilled units surgically obliterated by the AI, however, if you like a single player game where you really have to think about tactics, ranges, cover and elevation etc, rather than Tank-rush the nearest enemy (this doesn't work, and since resources are very limited, is a waste of tanks).
Oh yes, forgot to mention, I have, at least, found out where Supreme Commander got their waypoint system from, the system used by TAW is almost identical in a lot of ways.
