This game is like Diablo II + Heroes Might and Magic, both my favorite game. That mean this is better than them. There might be more enemies, monsters, bosses. More characters like archer, wizard, sorcerer, paladin, necromancer, warlock, knight, rouge, assasian, barbarian etc. And more items. And if you can make it bigger, more complex and funnier I can pay for it. 5/5 - 10/10 - 100/100 - 1000/950!!!
Have a look at the trailer for the main game: The link is in the game description. The gate allows travel between different parts of the world.
