[quote name='Apathetic-Irony']The game is very rock-paper-scissors based, where it goes Vehicles>Infantry>Air>Vehicles. As such, multiplayer seemed very shallow.
With that said, the game is well worth ~$27, if only for the single player/online co-op campaign and single player skirmish matches alone.[/QUOTE]
If you want a Rock-Paper-Scissors game then Endwar is it. The game only has around 7 units... (2 being infantry and 1 being a command vehicle).
I got Halo Wars the day it came out (limited edition for $10 less... yay.... still $60 though). There is an achievement for playing for 24 hours and i got that through only playing in the campaign (my and my brother co-oped it twice). So you can play this game a good amount.
Now i like to get about $1 to game hour ($60 should be played around 60 hours... doesn't happen a lot) and this one didn't do it for me. I'm not much for the skirmish only online (which is why i love Blizzard) so the online was kind of lame to me.
If you want an RTS (sorry RTT) that is inovative then check out Endwar (fully voiced... and it works amazingly well, but the entire game is shallow). Halo Wars is a good all around RTS. Controls work fine (for a console) and the game has enough depth that it doesn't feel completely rock-paper-scissor.
