SuikoDel is one of my favourite JRPG series. Even though the first few never really came to PAL regions, the last couple instalments were enough to hook me. I like what they did with a tactical spin-off like the one Fin-Del Fantasy did, even though it wasn't quite as good.
I really appreciated shion's Let's Play of SuikoDel II. It was the second, right? Maybe the first... Hmm.
