I don't know about you, but Halo Wars reinvigorated my hopes for the franchise. When I heard they were making this game, and ODST, imagine my pessimism. I always thought Halo was good as it is. A trilogy about the Master Chief against the covenant. It felt like they were milking the franchise.
Playing Halo Wars though, it doesn't try too hard to be a PC RTS, and for that it succeeds. Keeping the structures confined to the control base itself is a great thing, and a bad thing. It's a great thing because then players won't feel too overwhelmed on where to place structures or turrets. It's a bad thing because in RTS games. Placing ANY structure close to each other is a big No-no since you'll end up being more prone to getting attacked severely.
But in spite of all the small problems this game has, I enjoyed it, and this is another triumph for Ensemble Studios. I can see a bright future ahead for the series.
