So about 40h in - in the very last battle of the game. One of my top 3 FE's of all time, though the story clearly does not make sense unless you play all routes, including here the hidden fourth route. Gameplay-wise, it is a very polished SRPG. The soundtrack is incredible.
Now that I'm finished gushing, let's explore some of the downsides.
Rough looking textures
This is particularly evident when interacting with Seteth, as his robe's textures are suuuuper pixelated. Images above were captured from the game by yours truly.
The skyboxes are also very, very low-res. Look at these clouds:
720p even when docked - Yep, no 900 or 1080p, no siree. Even then, the game still suffers from stuttering and occasional slowdowns in some of the more crowded areas of the Monastery.
Lots of unexplained systems - I've playing FE for 20 years so I dove right in, but some of my casual acquaintances were completely flabbergasted by some of the mechanics, as they were explained only in passing or not explained at all.
