Hey thEClaw! Long time no see, what's up?
We will see what's the gameplay like on the map, and depending on that I can consider adding air units later.
The reasons of why they are not available, are the following:
- visual tricks: some of them are more appearent when you are higher, so it's a design/immersion thing
- smaller player numbers: I think at least a 8v8 match is required for the aeros to function properly - often there are smaller games now
- smaller map size: again, more suitable for smaller games
So basically every map is the product of the circumstances. For example Warzone is huge, with all units, designed at least 10v10 games... back then when I created it, there were often matches with 24-28 players, so it was suitable for the situation. ValleyForge is adapted to the current state of the game.
Anyway, thx for adding it to your servers! I hope that there will be some games on it!
