(1) Can a game still win without a battle system? I ask this because I am planning to make a visual novel RPG using RPG Maker MV. I hope you consider story based game.

(2) The submission should be in windows PC?

(3) Should it be a complete game?

Hope you give me some answers before I start this game jam. Thank you 🙏

Hi!
1) Battle system is not a requirement. But can it win? Depends on voters!

2) Windows PC is most common platform, but there’s no hard rule against others. It just may not be playable by as many people. You can do multiples platforms if you really want.

3) Doesn’t have to be a complete game, but I would suggest some sort of story arc that completes.

I am not an admin, but I think it would be wisest to deploy your project to Windows at a minimum, and web if possible. Since players will be given 3 random games to evaluate, we don't know what operating systems those players will be on; speaking from experience, deploying to web gets the widest player base and virtually guarantees that your project will be playable by everyone.

I think KV makes some good points.
