Team Ninja really missed a trick by not having a PS4 version of DoA5: Core Fighters ready at or near launch.
In this dark age of free to play and microtransactions I really feel like Team Ninja have done the AAA console FTP experience better than almost anyone else with the Core Fighters game, and they deserve praise for that considering how badly everyone else has been fucking up.
No cooldowns or tokens to fight, all modes bar story available for free, rotating free characters so you can try before you buy, and the vast majority of the paid content is costumes that don't affect the game, and yet that's where they make their money.
It's entirely possible to download the game, pay 8 bucks for your favourite two characters (with the 4 ninjas permanently free), have 10-12 free costumes for them, and then play without any nagging or issues at all for months on end. It's really a brilliant system, and they're one of the only companies I'm willing to buy DLC from because of that. Well, they would be if that shit was priced fairly. Which it isn't. But you can't win 'em all, and the fact that the FTP structure is good is far more important than the fact that the costumes are overpriced.
