This whole hybredization idea will turn a good horse into a mean camel.
I have had players who could not bend themselves around Hero, and I compromised for years, until Hero 5th came out. I still like someof the friends, so I (and a friend) started weening them off other systems. I still run other systems, but I alternate games to get them more familiar with Hero.
One of the players who originally hated the idea, now is looking forward to her turn running a Hero contemporary game, or perhams a superhero game. All of the players in the core group have come around one by one.
This strategy worked a few years ago too, but I my group changed out a bunch of players and we had to start over.
Ok fredrik_nilsson perhaps this is not the advice you wanted, but it is good advice from a 28 year gaming veteran who has introduced countless players to gaming, and Hero.
Good luck either way.
