Game has the same kind of quests. Fetch herbs but you just haphazardly mow over most of them. Save a farm from bandits except you're just blasting them. Kill quest to take out some liches tower but you just blow it up instead of raiding it.
All the npcs treat you like you're not a tank and are baffled by the way you complete their quests. Maybe get really absurd by completing some kind of mount upgrade where you're just a tank on top of some huge horse and it doesn't really make you any more mobile than before.
Yes, like an Isekai. Except you're a tank. You're just a tank, that's your whole body.
Actually new idea: you get like swords and armor and stuff but it just gets attached to your tank haphazardly. Maybe even continuously, like there's no limit to the helmets/armor/swords that you can keep slapping on your tank but they never really make any difference besides making you look more and more absurd until you reach the endgame where you're just absolutely covered in weapons and armor.
You reach the evil dark lord at the end and hes the only one who even recognizes that you're a tank covered in an absurd amount of gear and is just frightened and baffled
