Hint: Chilvalry is of utmost importance
um: I would say Chivalry Medieval Warfare (Windows), but that is a pretty huge game... also, (playing roles, maybe) not a strict rpg - it also has a duel mode (so it maybe meets all criteria) - but, wouldn't it be too good to be true? It is Steam only which would be a new thing since we always have a standalone copy. Mount & Blade (Steam only) also maybe too huge. I'm stumped now since all searches including "medieval" "chivalry" even if you "-warfare" still end up yielding Chivalry Medieval Warfare for all search results.Edit:
I have since read the description for Pixelry
and it looks dead on for the feature. Definitely would pick it up. I think GnomeSlice guessed correctly on this one and before most of the hints. The only thing that doesn't add up is that it supports Windows and Linux and one of the hints was "win pc".
