I've been in an RTS mood lately and I didn't want to get back into Supreme Commander. I was looking for a large-scale RTS and for some reason I remembered back to when I would watch my buddy play Empire Earth. The Total War games haven't interested me since Medieval 2 and I just got done playing a few long campaigns a few months ago.
I was thinking about starting up Age of Empires again or Total Annihilation, but I've played those so many times already.
You should give a try to:
º Warhammer 40K: Dawn of War (first one, along with its expansions)
º Warhammer 40K: DoW II (with both expansions, namely Chaos Rising, and Retribution)
º Company of Heroes (first one)
º Grey Goo (don't let the stupid title stop your curiosity, watch some footage on YouTube and check its page on Steam; seriously though who came up with Grey Goo and then thought "
OH YEAH! That sounds epic!!!" ? It's beyond me)
º Homeworld: Deserts of Kharak (new game that's apparently a prequel to the first Homeworld, check it out on Steam)
I am a total Warhammer 40K universe fanboy, however, that much I can admit. So since I am completely 100% biased I'm going to tell you that if you never play DoW (the first one, especially with the Dark Crusade expansion) then you'll never be able to claim that you've fully experienced RTS in your life. Yup, I tell ya. If you do buy it along with its expansions you'll most likely get Soulstorm as well. If you do, then you'll need the
Bugfix Mod to experience it at its best (without that patch it's another story, and you might just as well skip it entirely, but it's really good with it). And obviously I'd also recommend DoW 2, Chaos Rising was good and so was Retribution. However, base building was removed in favor for more action. If you prefer base building (like me) then go with the first DoW, get Winter Assault and Dark Crusade (and possibly Soulstorm) and then be blessed by the best WH40K game ever made so far.
