Simmons could've been a better villain had they build him up over the course of a few games instead of introducing and killing him in 6.
Technically they did. Simmons is the personification of the American government's collusive relationship with Umbrella and its more unpleasant affairs, such as holding Sherry hostage and threatening to kill Leon if he didn't work for them. He's the man who negotiated with Birkin to acquire the G-Virus too, because he didn't like having to buy from Umbrella.
He's also the lieutenant general in Sherry's BIO3 epilogue.
Still, they shouldn't have killed him or made him an Ada fetishist.
Interesting, but I will say, in English at least, the goal, purpose, and even really just what exactly Neo-Umbrella is hardly touched on, and when playing the game it's really easy to forget they even exist. The Family stook out a bit more due to Carla and Simmons taking the villain stage in that game. which they may be involved in, but their goals and purpose with Neo-Umbrella wasn't well handled in English, at least. Still, I felt Simmons got way less screen-time to be developed into someone proper interesting, a kind of wasted opportunity.
Yeah, I agree. They don't explain the relationship between the two organizations in the game outright, you're left to pick up on slight details, which is awful. The way it's portrayed in the game, you'd think Carla Radames founded the organization, when really she just took the name from Simmons' own organization as a "fuck you."
