First let me sy that I got this for a steal on sale, so can't complain too much, but
Graphics are ok (cir 2005 style), blocky 3D but effective enough
Typical RTS Gameplay, not much reasource management, just drill for Oil -> Money, focus on combat and base bulding
However, overall, this is a pretty flawed game, based on what I played at least (US campaign, then got bored).
Its tough even on normal difficulty, odds are often stacked against you, and silly restrictions (in single player campaign) such as this 1 unit must survive, and no repair capability offered, even between levels!!!?
Enemy AI is pretty simple, but effective enough... units will stay where they are, didn't see a lit of patrolling, and then they swarm as soon as you attack. Own team AI is where most of the problems are... can only set 3 basic tactics per unit/group... chase 'em, stand still, or stay within area. Even on stay within, you units often roam into areas they shouldn't and get picked off easy. Wost part is the route finding... the game relies on building many units and swarming when you outnumber the enemy... often groups of 15-20 units per group. But the pathfinding is bad. often the first 3 or 4 units head in the right direction, and the ones behind bump intoi them and then head off in another direction for an alternate, often with disasterous effects.
Base building is pretty noddy too. no sign of upgrades for most buildings, just build one to access a certain list of units and then forget it. Having to manage power was a nice touch (each gen can power two nearby buildings) which gives some tactical options of blacking-out your enemy buildings... but most of the time you'll get mashed before you get near ur enemies gens.
All in all this seems a dissapointing basic RTS cir 2000... if you want a very cheap nostagic RTS shot then grab it on sale, if not avoid, there are much better ones out there.
