A lot of the times the serious hacks on this board... are well, not good honestly. They have the same exact gameplay as every other hack and while I appreciate the effort and the hours of work, they're not necessarily all that fun.
Here's something that's unique, and while it's not an extraordinary example of hacking, it manages to not take itself seriously and is a short, fun ride.
Hinkage, if you havent already please play Pokemon Snakewood. You two are very similar... however Snakewood has a huge emphasis on unique gameplay puzzles in addition to the crazy humor and storyline. Pokemon Warped is another similar example.
It's not great *hacking* per se, but it's a fun hack to play. Don't let the immense criticism get to you.
