In recent months, a number of video game publishers have publicly talked about pulling back Wii support, particularly when it comes to core or mature content. In fact, today a survey from Game Developer found that Wii development dropped from 42 percent last year to just 30 percent this year. Naturally, BioShock doesn't seem like the kind of property that would fit the Wii audience, given these trends, but in our recent in-depth interview with 2K Marin's Jordan Thomas we decided to ask him about making BioShock for Wii anyway.
"Nothing beyond speculation presently," he answered, then adding: "Anything that's brought to the Wii tends to need to be purpose built, or fairly fundamentally re-architected. There are few games that use Unreal that made it across to the Wii. It doesn't mean that it's out of the sphere of possibility, but it's not something we considered for BioShock 2."
Considering that 2K took BioShock online with multiplayer we asked Thomas what might be next. We brought up the idea of an MMO, but he seemed to hint at co-op gameplay.
"Personally, I value the intimacy of the BioShock experience. I have not seen an MMO successfully convey that, but that doesn't mean it's impossible. I would be more interested – speaking purely hypothetically – in a BioShock- like game that explored more personal cooperative play, rather than a big amusement park style design," he said
