island systems is like stellar systems, a nice transition to make bots world Eve-like
adding continents would make the game slightly different, might be too risky 
and maybe engine can't handle them, but would be nice yeah
btw, what about more way to travels, more mech ?
planes ? i don't know if there are some rp who stop flying abilities, i don't think flying controllable bots would be playable and balanced, but were thinking about some drop zone system, a plane (or something else) pickup and drops bots at a location on the map or a transport & transport-launcher who is fast enough to carry other player-mech and launcher one can even throw them at a loc by drop system
but that would fit for larger maps
mortar-mech, in this game we have the ability to select tiles, what about a targeting laser mod used by a scout to lock a tile and a mortar mech in his group can see the lock on radar and AOE the place from very long range, probably the whole island would have to be in his range. For a moving target once fired it will boom the tile were the target was.
But might be hard for dev to make this work
more eve-like,
a stealth bot who can do scout duties like searching for mortar-mech location
a carrier mech who use lil' flying/walking bots
large mech/vehicules would need terrain designed for them for being able to move all around the map, some place they can't reach, littles can escape from them, continents would fit better.
