For 100k, I’ve got a couple of stretch goals.
-Drinking mini-game (but not really). Not so much a mini-game but just put consumable alcohol in the game (and not like skyrim either, make a drinking animation). Make it so you can drink way too much and then go careening around the place or black out if you really drink too much.
-Add crossbows or maybe slings. Throw in some javelins, throwing axes, or even daggers.
-Put decapitations in fights. Like when you do a high horizontal swing with an axe or a heavy bladed sword, their heads comes off. Maybe some impaling with thrusting weapons as well.
-A bunch of tavern songs that the npcs will sing whenever you go by a pub. Could even add a minstrel or a bard. And make the songs they sing relevant, like if your deeds become widely known, make them sing about your exploits.
So there’s a couple of ideas, honestly though, I’m just looking forward to a good game.
