I think there should be lots of recruitment options. You should be able to gain permanent allies but also be able to use mercenaries. It's fun when party is dynamic and some would join your party only for brief period of time. It would be nice to see that some members have agendas that they want to pursue. Like when party gets rich enough some might want to split gold and be on their way. If you say no they might become hostile. Also not all party members might get along so you should choose carefully who you recruit.
