I used to really enjoy the RTS games back in my PC gaming days, I played a lot of the C&C series, Startcraft, Dune, etc.

One of the last C&C games I played was C&C 4: Tiberian Twilight, which I found really disappointing because they took out a lot of what the RTS games are really about, ie. Building bases and armies. Seemed like they were dumbing it down.
