Some friends and I have been talking, and we came up with some ideas that would be cool in the update after 3.0:
1. A new vs. Mulitplayer. Instead of playing as the evil, both players are a hero!!!! And each player gets a castle/keep, and the first one to kill the opponent hero or destroy your opponents keep wins!!!!
2. An evil campaign. I know that the game is heroes and castles, not villains and castles, but it would be pretty cool if the evil side had their own campaign, even if it's just 10 stages, that would be quite fun!
3. An evil betrayer hero, like a skeleton or mummy, or even an Orc that has joined the king and has turned good.
Well that's about it. feel free to leave some of your ideas in the comments section!!!!
