It bears repeating, Caspian has renewed my interest in the beta and the game itself. Thinking back, its amazing how much Metro soured me on the game, I even considered not getting it.
Caspian is pure Battlefield. A well designed map, not perfect, but very very nice. Each CP it's it's own little discreet battlezone, with fields, forests, rivers, and roads between them that are just a joy to traverse and advance upon.
My biggest gripe is that what's going on in the air seems almost completely removed from the ground war.
Battlefield 3 begs for its El Alamein! I NEED THIS.
