There is a saying... To a reader who encounters an old classic for the first time, its new. ^^
We can't assume that all the players have seen it before. Many players are playing original versions and have not had it before. Plus there's always the collectors.
The problem with hacked games and hacked content is, they take away the main part of the experience -- the anticipation.
Another problem with hacked content is, the old data usually changes just before release. The Tiny Dragon, for example, had Atlas' specs until just before release. It is now a Nature-Light Hybrid. Different Elements = different Attacks.
In summary, there really is much about hacked games and hacked content that dilutes the experience and the gameplay.
The only commendation I can give for hacking games is that you have an option to make the experience richer and more fun by making it harder than what the normal user would like (developers have to cater for the normal user, after all) and spending more time on the development of its characters than the Developers would (they have costs and budgets that limit this to reasonable figures, you don't.)
However, as you can see around you, it isn't happening. So players of hacked games are really losing out.
If you have ever played Quake or something similar, you might have an idea what I am talking about. One of my fellow players hacked the game to make it more realistic -- no line of sight shooting, you have to allow for drift and lead the target. Wounds slow you down. And other minor details. And you can add detours and small quests in adventure games that add to the character development.
When I look at what people are doing to DC, I just have to shake my head. It's just not the good way to hack a game. All you get are lots of dragons, nice numbers to report, and pretty dragons. How much value there? How much thought into it?
Conclusion? Modern hacks are boring.
