Final Fantasy for sure.
It's the most hyped I've been for a a new mainline FF in like 20 years. I like everything they've shown so far, combat looks like a ton of fun, it has that large scale epic scope I've been wanting to see in more games, the story has the potential to be one of the best in the franchise (at least compared to these past 20 years), I like how it's not open world and I like how it's supposedly "only" 35 hours for the main story which is the exact opposite of one of my biggest issues with modern JRPG's (the never ending bloat).
Tears of the Kingdom is probably going to be a very solid game and will probably have the more unique gameplay and interesting world design.
But nothing they have shown has really excited me, it's like they've gone out of their way to make it look like DLC. If we get a new trailer showing substantial improvements to gear, combat, enemy variety as well as real dungeons and good bosses I'll be hyped.
