Would have preferred no limit at all, or at least the option for two weapon and a pistol/sidearm. Better yet would be one weapon per slot, for a given number of slots (ie. sidearm, automatic, close-range, heavy, long-range, explosive).
Saying that, the game and its challenge were scaled to accomodate and it's good enough a game that one can forgive it its few flaws. 2 weapon restriction was much less annoying than the single-slot "autosave" in lieu of a proper save system. Fucking consoles. I would've also preferred two currencies so that Vigor and Weapon progression weren't in opposition to each other.
Anyway, great game, didn't understand the ending whatsoever but still looking forward to whatever future content the Season Pass gives me down the line. But first, I have 1999 "Scavenger" mode to complete!
