You should have probably figured out that there's a reason I put so much Wario Land 4 stuff in my works. And that's because to me, Wario Land 4 is one of the greatest platformers or games of all time.
As of now, I've used the following Wario Land 4 level GFX and themes in End Game:
The Curious Factory
Forty Below Fridge
Pinball Zone
Toy Block Tower
The Big Board
Domino Row
Crescent Moon Village
Hotel Horror
Golden Passage
And these ones in Nightmare Quest part 1:
Palm Tree Paradise
Mystic Lake
Monsoon Jungle
Toxic Landfill (planned)
Forty Below Fridge
Toy Block Tower
The Big Board
Doodle Woods
Domino Row
Hotel Horror
With Arabian Night planned for part 2. So yeah, pretty obsessed. So much so that I've literally only got four levels out of eighteen that I haven't used GFX or ideas from...
And I'll probably end up including something from each of the last four somewhere in the later parts of this game...
But yeah, fan art, fan fiction (before), board games, ROM hacks, sprite rips, Wario forums, Wario music on Youtube, Wario discussion on other sides... I am pretty much close to obsessive about that game.
In other news... expect a possible delay between part 1 and part 2, because I'll probably take a break then.
