Persona 4 is gonna rock my world when it gets released, though there is no release date for a PAL version yet.
In any case, I've been a fan of the Shin Megami Tensei series ever since I rented (from Blockbuster) the third game in the series proper, Lucifer's Call/Nocturne. Now I can't get enough of the demons and occult settings of the SMT series and its spinoffs (Persona, Devil Summoner, Demikids, Last Bible etc). The series is great for people like me who have become burnt out on fantasy setting after fantasy setting of other RPGs, and somehow the modern setting never gets old.
For DS owners, Devil Survivor has been announced and there are pics of it on the internet. It's an SMT game set in a quaranteed Tokyo where a bunch of teens are left alone in the demon infested city. Plenty of talking to demons and fighting action, I look forward to that too.
Lastly, Hee-ho! (If anyone doesn't get that, leave the thread now)
