I've thought for a week about this, and I am currently thinking to release the game as "pure VN". It will probably be around 200k words, it has a lot of choices, endings and 32 (yep, THIRTY-TWO!!!) different CGs, so it's not like there isn't enough content for a VN...
A card gameplay was out of question of course. I thought about RPG gameplay... but the kind of setting won't work as RPG, since the game was made to be team vs team battle. There's no "journey". You don't travel to defeat an enemy evil like Loren, or escape/survive like in SOTW.
A pokemon gameplay MIGHT work. But yet, if I've learned one thing this year, is that the only kind of game in which people like to read, apart VN/Dating Sims (obviously!) it's RPG.
People who want to play card game, fire up Hearthstone/whatever and just play. They don't want to read a 200k words long story
no matter how good it is. If they wanted that, they would play a visual novel, dating sim, adventure game, etc (a story-based game).
I will go in detail in the next Friday's blog post about this, but I've (finally lol) realized that the worst thing is to mix two kind of games/gameplay that aren't compatible.
Of course there's still time for UL release. I might come up with some simple gameplay idea, something that could work in the contest without being too much work. We'll see
