God cant believe how many of you havent included company of heroes. /shocked
@ Deepjay,
That's because to some of us, un-limited ammo and fuel (etc.) are bullshit tactics, and something like Men of War with inventories for each and every single battlefield unit is a much more fulfilling experience!
Men of War? Gee, buggy and with a tough control system.
Soldiers: Heroes of World War 2 - now we're talking! (Except the voice acting, that's rubbish...)
And my list:
1. Command & Conquer (Tiberian Dawn, for those that will) - the game that got me into RTS, humor, great music, great action and one of the first real RTS' games ever.
2. Homeworld / Cataclysm - Epic, there isn't much more to say. The campaign, the music... the atmosphere (no pun intended) is just breath-taking. (I still get shivers down my spine when I think of Kharak burning... And the soundtrack... The Yes song is pretty darn good to be honest, 29.AIF in the game's music BIG file.)
3. Company of Heroes - one of the best modern RTS's, nuffsaid. Awesome music, graphics and feeling. No it's not a Men of War - but hell, Supreme Commander... Tiberian Sun...? I think those lack more realism than CoH does. The expansions and patches have kinda changed the game (back to CoH) in a way I don't appreciate to 100% though. 1.71 was a gem.
4. Warcraft II - Blizzard. Do I have to say more? Ok then, in one word; "hilarious". Awesome and really huge game. (If you haven't played it, you should. Especially if you've been playing WoW - I've heard there are people that actually do that - you'll learn a lot about the Warcraft lore. (Which is really interesting.))
5. Dune II - Almost the first real RTS, and I remember playing this on my good ol' Amiga. There's some things that really, REALLY stand out in this game; the music (almost nothing gets your blood pumping as Frank Klepacki's masterpieces), the Dune universe and the very well balanced missions. (Not too easy, but not too hard.
Notable mentions: Age of Empires series (lacking in advanced strategies though, even in AoE III - as there's no cover, no defensive positions, no bonuses etc. etc.) - still good games.
Dawn of War series - really good games, not really standing out in any areas though, unfortunately.
C&C3 - surprisingly good, considering it's an EA piece.
SoaSE of course! - little too long games and no real missions. With the perfection of those two it'd climb the ratings really fast...
Soldiers: Heroes of World War 2 - one of the few really good RTMSS (Real Time Military Sim Strategy) games, realism to a relatively high degree and awesome graphics and physics at that time. Big minus for using Starforce though.
Act of War w. expansion High Treason - after beta testing those puppies for a loong time they finally hit the shelves, and they were really good! Also had the problem with not really standing out in any way though. Still good games.
Settlers II - Blue Byte's brainchild, small cute pixel built persons running along roads with materials, really good, and a true classic.
