I bought this game because I loved the original Dawn Of War and expected more of the same. I should have read the review first because this game is nothing like the original.
First off I don't know how they can call it a RTS game. It isn't. It's far more like a RPG. In the campaign mode, there is no base or unit builing, no strategy or tactics. All you do is move across the map killing the enemy. Yes your units have different strengths and how you use them determines your success and you do control your units like a RTS game. But that is the only RTS element there is.
The rest of the game is RPG, you upgrade your units with weapons and armour, you gain point's from missions to enhance their abilities/statistics. You follow a linear mission based storyline than has no variation determined by your mission choices. There is a game for consoles called Space Marine coming out, DOW2 looks like the precursor to that game. They would have been better off giving DOW2 a different name.
Now for some positives. After I got over the dissappointment of the games format, I really enjoyed this game. It is great fun to play. Some missions are easy, some are very tough, the action is generally fast and furious. The graphics are great for the genre.
I was a little dissappointed that the Marines can only be levelled up to 100, which restricts what stat's you can upgrade. This becomes particularly important when you play the sequal 'Chaos Rising' as your marines stats and equipment carry over to Chaos Rising. So you need to think about your upgrades.
Another complaint is that you only play as Space Marines. Although there are Eldar, Orks and Tyranids in the game, there are no campaigns for them.
There is a Skirmish mode in the game, which is more like the original DOW. You build a base and units and capture resources and can play as any of the 4 races. But this mode is so small and limited (you only build a few structures and are limited to fielding only several units at a time) I've only played it a few times then didn't bother again. If I want to play the skirmish format then I get out the original DOW instead.
Finally there is the installation. This is a veritable nightmare. If you already have a Windows Live and a Steam account, then that helps as you'd have to create one during install (like I had to). Even if you do have these accounts it still takes ages to install. Took me well over an hour the first time, due to having to create accounts. Thankfully this Game of the Year edition has all the updates that have been released since the first edition and this shortens the install considerably (the first edition had huge amounts of updates at the time of release).
Overall there are good points and bad points (more bad points unfortunately), but the game itself is hugely fun and worthwhile and I do recommend it especially at this low price. It's a shame thoguh because the game could have been so much more.
