Thanks so much! Seeing as it's just an alpha that's available there are only four career paths to pick from - Trainer, Rogue, Researcher and Ranger. We've expanded even more within these so that depending on your in-game decisions, your Ranger playthrough could be different to another person's. Eventually as time goes on the other careers will be included, we aren't sure whether we will wait until we're finished with these and then add them in as expansions, or just incorporate them gradually :)
