I preordered the game and downloaded the beta a few days ago, and I'm really enjoying the game so far (I don't think I've ever played a beta with less bugs

). Haven't been here long though, so I don't know if this has already been suggested. (or if it's already a feature

)
Anyways, I started thinking about supply lines (à la Company of Heroes) yesterday. Basically, the idea is that if a planet is not connected to your home planet, directly or indirectly (via your other planets, allies, empty planets, etc.), you won't recieve any income or resources from that planet. So if your enemy has a huge empire with a few choke points, you could target those planets in an attempt to isolate as many planets as possible and cripple his economy. Alternately, you could take a fleet and make a blockade at any point on the map (including asteroid fields, empty planets, etc.) with the same effect. The "Gateway" map would quickly become even more interesting with this

It does raise a few questions, though: Do isolated planets have access to the resource pool? (that is, can you build stuff there?) Why do they suddenly stop mining/paying taxes just because they're cut off? Why not just go around the blockade? And so on. Regardless, I think something like this could be quite interestng gameplay-wise. Oh, and I realise it's a bit late to come with feature ideas now, but maybe for a later patch/expansion?
Thoughts?
