The game barely has a player base in the US. You may find more luck in some regions than others, but your best option is to seek discord or whatsapp groups, or communities on either platforms before you decide to buy.
It's a shame really considering the gameplay depth and amount of content that the game offers. Also, 14 is a far better entry point than 13 was. And contrary to what many believe, all 54 characters have a competing chance if you put on the effort to learn them.
PS: if anyone would like to try the connection with me on PSN, my ID is "Alucard-XII". I got playable connection with one of my friends who currently lives in the US.
