I'm working on building up an Armored Core collection. Which I guess would include other From Software mech games.
At the moment I've got AC2, AC3, Silent Line, Nexus, Last Raven, For Answer and ACV - leaving AC1, Another Age, Nine Breaker, Formula Front and AC4 and Chromehounds before I have to start branching out to other regions (Project Phantasma, Master of Arena, Metal Wolf Chaos, maybe even Steel Battalion some day).
