Which version of Heroes do you like the most?

1) I'm currently installing 1 and 2, and I'll be playing them. 2) 3. Heroes are undeniably the best! 3) 4. Heroes would be better if I didn't even know this game existed. I installed it, played for 5 minutes, and uninstalled it. 4) 5. Heroes has a bad storyline, but the graphics are decent. We'll be waiting for the next expansions; the last expansion really pleased me!
