For me, Capcom had really annoyed me last generation. Since my favourite franchise is Resident Evil - they had a really poor showing on last gen. This generation they managed to win me back with a great game in RE7, a decent showing in Revelations 2, a remake for RE2 as well as ports/remasters for my favourite classic (REmake) and other games such as 4, 5, 6, Revelations, etc. I'm now a fan of Capcom again and excited for the future.
Do you have any stories of a developer who has won you back?
I might be jumping on the capcom bandwagon, but only and I mean only if they give me an old school looking Megaman X9 game. None of this 3D model crap.
Otherwise, those who have betrayed me have yet to win me back.
