Bout the best its going to get in the rts community for another several years.
The game is probably the most skill intensive rts to come out since the grand master rts: warcraft3. Warcraft3 had alot more challenge and skill admittedly, but this makes all other rts's look like exercises in noob wars that have come out since then, and has sweet graphics and some really cool units.
It really has a good artillery and tank system as well as several tricks you can pull out of your hat with every army available, and there are alot of armies to choose from and they've all got tricks up their sleeves.
I had always been a 40k table top fan as a kid, so this game might have special appeal to me, but like all the dawn of war series before this one, you can paint and customize your armies in a pretty cool way. Even the emblems and flags they carry onto the field got my personal touch and it took minutes to do so.
If i have one complaint, its that relic used gamespy to host the series, and even since the beginning this left a lot to be desired, and the online community never developed into what it should have.
