So, just why exactly do ships not automatically fleet up in orbit? (They only do so if you build the orbital fleet manager whatsit available midway through the game, thus spending money and space where you may not need to).
I can think of a lot of reasons why fleeting in orbit *should* be automatic:
1. It would help un-cripple the AI. Even at tough level, the AI obviously can't keep up with a human player's manouvers, and as a basic fact it keeps multi-ship forces in orbit around its planets. Those forces are picked off piecemeal. If they were automatically fleeted up they would be militarily useful defenders.
2. It would rid human players of tedious micromanagement in frontier areas. Basically, this game seems to lack any convenient "alert" feature to tell you that an enemy fleet is sneaking up on some obscure world while you're paying attention to the other side of the map. I've actually had worlds invaded because my defenders were properly fleeted up, and thus *not in orbit*, while an enemy just waltzed right in with a transport.
3. It's just plain realistic and "feels right" for new players. Brad wrote in some interview somewhere that he likes simulations where players can go more by feel. But there are a lot of places in Galciv 2 where, at least to me, it feels wrong and counterintuitive. Since most people on these forums are obviously not new players, perhaps my perspective on this one might be valuable.
Probably one of the reasons it's counterintuitive is that in almost EVERY other military game out there, including and especially Civilization, defenders of a city or other center of power have an *advantage*, not a crippling disadvantage.
I really think that changing this game mechanic would be just a win-win situation. Especially because it doesn't seem like you'd have to change the AI much (if at all), given that the AI is already leaving bunches of ships in orbit around its planets.
