Didn’t DA:O also limit equipment to melee/ranged setup?
Yup ...
Honestly i believe i never played any game, that would allow you to have anything on second set of weapons ...
Maybe except Diablo II. ?
Have you never played Baldur's Gate and all other infinity engine games ? Pillars of Eternity and other Obsidian games like Tyranny ? Pathfinder ? Solasta ? Wasteland ? the recent Expedition : Rome ? Black Geyser ? Encased ?
Just a few exemples of role playing games but there are a lot of games that allow you custom weapons slots.
I can only think about Kingdom Come Deliverance and South Park : The Stick of Truth that limit you to melee + range.
But those games aren't tactical games and/or doesn't have a lot of weapon types. Maybe The Age Of Decadence too, but I'm not sure.
