It's a great fighting game with a fantastic roster, and the single player features like Classic mode and World of Light are all fantastic. However, as lockdowns for COVID started and I was forced to come to grips with how bad the online is, everytime I play this game I get frustrated with how awful the netcode is. It's simultaneously a great and awful game. I have no desire to play this unless rollback netcode is implemented or I can start playing it irl with other people again. I can't in good consciousness give this a good rating with how broken the online is. To make matters worse, most of the playerbase refuses to use ethernet cables, and it has all kinds of other technical issues like built-in input lag. even Smash 4 online was better than this.

This port is interesting to me, because on paper it has so much that makes it look better than the DC original, but in execution it's littered with weird bugs and jank that wasn't there on the Dreamcast. A lot of collision detection issues were introduced here that makes the game look really bad. I can't believe the modern ports never fixed the bugs in it.

The Dreamcast original is probably the best iteration of this game. The graphics aren't quite as good as DX, but this version doesn't have the jank or bugs that were introduced in the remaster. The only real problem I had was the occasional long loading screen and slowdown on Skydeck. Hopefully this game gets a better port soon that's more representative of the original game.
