Maybe I should get around playing IV. I kinda don't like it though but it's the only mainline Suikoden I haven't finished.
Any tips on how to beat this game quick while getting all the 108 stars? I wish the difficulty would be like Suikoden V's: being able to kill bosses in one turn only.
Suikoden IV's battle system is pretty streamlined and made minimalized. Basically its quick engagements. There are a bunch of tricks in FAQs on super quick power-leveling. There's even a training center in your HQ for you to power-level in. If you do however play IV, play Suikoden Tactics right after. They go hand-in-hand basically - compliment eachother really well.
