I'm on the opposite side, I really like this limitation. Games almost always quickly end up with words / numbers in there somewhere so it's nice to have to go against that grain and try find ways around it. I think any theme / ruleset will make certain games difficult or impossible to include. That said - you could challenge yourself and try create a game in one of the genres you mentioned. An incremental game could be like a pig you keep feeding and it gets bigger and bigger and bigger, no need for numbers. A game focused on resource management could have resources be physical objects in the world rather than numbers to represent the amount.
Just my 2 cents. Good luck and have fun if you do decide to take part!
