It's great to hear that the game is doing well beyond expectations, though Aki-at brought up thoughts I've had for a while. Where do we go next? What does this mean for Valkyria?
Short term, I'll echo that maybe SEGA should get Platinum on the horn and get Vanquish (Bayo 1 as well?) ported, or inhouse possibly get VF5FS/Skies/other highly requested game ported. Would Resonance be as welcomed as VC was? I loved the game and put a whole bunch of hours to Platinum it, but I'm worried about the notorious difficulty curve may turn off people...then again I would totally be wrong and people would love the game for it. I would hope for them to finally pull the trigger and bring out PSO2, just throw in all the SEGA cross-overs now that VC and other franchises are making PC appearances (the only one missing would Yakuza, right?)
As for Valkyria itself, I really hope that this means the series is getting another shot, but what to do next? I'm also worried that the downgrade with 2 and even 3 may do harm than good (I still want to see the 3rd game localized). A new entry is risky, but I'm hoping the PC reception encourages them to consider it, possibly doing both a console and PC release at the same time (limited print run for the former if need be).
This can of course also apply to other IPs/Games that they're either sitting on or haven't localize (but obviously not always guarantee success). Honestly though? I want this to be the open door for getting their catalog to interested and potential audiences.
