After playing it some more, I've basically found a few major problems with it. If you want to know them, read IGN's review. They literally cover every aspect that I don't like.
I'd probably give it around 80-85% so far. The biggest gripe I have is that the flora and level design make it so that the action is dispersed instead of concentrated like in BF 1942.
It's a good game, but I think I'll stick to DC until they patch it (or until the Trauma Team releases DC for BF: Vietnam
).
