Did you have this same reaction when both Sigma games were released? Especially 2, which was a glitchy and poorly coded mess even after they patched it until almost a year later? (how many of us remember having to play it offline in version 1.0 mode due to the gamebreaking error?) Suddenly these PS3 owners get three new characters, new weapons, new bosses, and more balanced gameplay, while we're left floating in the wind.
It strains the mind a bit don'it? You think you're all alone... maybe I come down the chimney, bring presents to the good girls and boys. Maybe not, though. Maybe I've always been here.
