Well I thought of a couple of idea's that might improve that game
For the High Res Texture Pack could we add in a pilot and gunners/co-pilot into the game, this could be a option? for players depending on how realistic they wish their game to be.
Tides, this will make attacks on bases more relistic and give bases on and near the shore a natural source of defence and make it more relistic
And another one i'll just chuck in, Waves: Launching LVT's will be a little more interesting
