I used to play the tabletop game (well i played it once) and it wasnt the easiest thing to understand, nor was it the cheapest hobby. I gave up playing it after one game as i just couldn't get my head round it. That was about 5 years ago.
However, childish as I am I still miss the cool Space Marines and Predator Tanks I used to build and paint, then relic announced they were making a RTS based on 40K, I jumped at the chance to be involved again without looking like a Kid. (no offence to people my age who play it, just proves you have more guts than me)
This game is fantastic, the looks, the playability, and the variety of gameplay are superb, from the general feel of the game as an RTS, to the full scale skirmishes you witness when things get up close and personal between the factions in close combat, everything has been thouroughly thought out to give one of the finest rts experiences available on a budget today.
Your System doesnt have to be pure gold either, my copy runs on high on all settings at 60fps on a geforce fx5200, a gig of ram, and a 3.0ghz pentium 4.
My only gripe is that the single player camaign Is a bit short.
This is a great rts that no rts fan should miss out on, even if you know nothing about Warhammer 40K
