The game is still being designed so none of the following is an absolute. The final design document will be presented immediately prior to the Kickstarter being launched. Playtesting will determine a lot of what the final gameplay looks like so even what's in the KS design document could change before the final game is released. Lastly everything below is assuming we reach all of our stretch goals. The minimum gameplay for I:B will be very simple if we don't raise enough money.
At the moment the plan is just for 2 faction/teams. We want to allow modding if we raise enough so that opens up all sorts of possibilities and of course there's always the potential for DLC.
Yes, you can choose and the server will likely auto-balance. The server will reset when one team wins the game.
The current plan is that each team starts with a pre-determined number of factories and space stations. Factories generate resource points over some interval X that are evenly distributed amongst the members of the team. Resource points, which can also be acquired by killing bad guys like in CS (maybe also through healing team mates like in battlefield?), can be spent to buy better ships, equipment, build more factories for your team, or build space stations (and possibly associated defenses?). Space stations come in 2 sizes: large and small. Small space stations can only spawn small ships like fighters and bombers. Large space stations can spawn both large capital ships and small ships. We're still discussing the possibility of having land bases alongside the space stations.
Yes and players can build new/more stations/factories/bases. The game will have a sandbox mode so ppl who just want to fly around and explore can do so on their own terms without being a hindrance to their team mates.
The game will have non-combat support roles but I can't provide any additional info on those atm. There will be no pirates or traders as the economic model will be very simple - you collect resource points and you spend them. Perhaps we could allow giving some amount of your resource points or equipment to another player but we currently have no plans for any advanced form of trading.
We fully intend for all 100-200 players to congregate at a single point - how else are you going to have massive space battles? We also hope players will be able to break off and do their own thing like take some of your buddies and do a strategic strike against a cluster of factories that the opposing team thought they could hide on some far off, obscure moon. For those who like to explore they can do scouting missions to try and locate enemy installations for their team mates to attack. We want to be able to accommodate a number of different play styles =). By allowing players to be able to build factories and space stations themselves we hope that will create areas of conflict that will provide players with new and interesting objectives.
If we only raise the minimum KS we will provide the objectives ourselves and the game will be far more repetitive =(.
