CLANGEDDIN'S PROFILE

There's nothing wrong with releasing new versions as long as it's improvement and new content added.
Ignore the naysayers and keep improving whenever you can, just make sure to take every step possible (this is the keyword, if it can't be helped, I suppose the players will just have to restart if they wish to experience the improvement) to make upgrades retroactive so that players are not forced to restart from scratch and it should be fine.
It's also a way to keep a game constantly fresh and having people interested on the franchise over time.
I'm looking forward to the ultimate edition, where I expect that the "Scenario" word won't be spelled wrong every time. :P
