I have the game on Switch, and I used to be hardcore sports gamer. This game will scratch that NBA Jam itch. BUT it definitely needs a gameplay patch or two. Too many air-balls, too many missed layups, physics are a little wonky, jump ball is awful, rebounding needs work. Defense AI and offensive AI can be awful at times. AI can be ruthless, and your team can be inept at times. Boxing out is missing, since players will stand around.
Rules needs to be able to be toggled on and off. Straight gameplay and with bonus rules. 4 point plays and perfect shot extra point bonus.
This can all be fixed with a gameplay patch or two.
I like the card pack system. The online needs to be flawless if they want to gain traction.
IF THEY TREAT THIS GAME AS A SERVICE, AND BUILD UPON IT WITH GAMEPLAY PATCHES, ADDITIONAL COURTS AND PLAYERS. THIS IS WILL BE A GOOD GAME. I believe it is worth $20, but I would wait for the first gameplay patch.
