Most of the 'sensible' interplanetary war stories start with cheap, easy FTL and fewish habitable planets. In which case conflict is likely for species that can use the same planets. Of course its a HUGE leap to cheap easy FTL.
One I remember that didn't have cheap/easy FTL had a species flee their dying home planet on a slower than light colony ship, and end up here. They wanted to come down and party with us, and we didn't want them to.
