>There aren’t enough characters for me to justify that.

the most recent iteration of SFV ("arcade edition") is $40 new and includes all characters released in the base game and seasons 1 & 2. you can earn an in-game currency to buy whichever season 3 characters you wish. that's 28 characters ready to go when you first load up the game and 7 more you can buy with real or in-game money if you want to. you *might* spend $70 total for the game and all the DLC characters
