What would make everyone happy is Capcom REmakes Resident Evil Gaiden.
That way, Leon's 3D model from RE4 can get recycled, and BARRY BURTON can make an ass-kicking jill-sandwiching NEW-GENERATION COMEBACK. It is the LEAST familiar setting among resident evil games, and its adventures deserved to be fleshed-out, and Barry's story be heard.
Without BARRY BURTON'S tactical prowess, combat experience, balls of steel, and training insight as a mentor, Leon would never have survived the years between RE2 and RE4.
It only makes complete sense.
And no, it's not on rails.
