DW8 XL on PS4 is free now on JPN PS+; already have it on PC, but downloading it to compare since I know now the PC version is based on the PS3 version. Haven't really put much time into the PC version so if I play it maybe I'll play it on PS4 now.
Japan PS+ is pretty cool if you don't import much these days. Only started using it since January, but already got EX Troopers, Clannad, Blazblue Chronophantam, Tales of Symphonia on PS3, Shinobi Versus, Tokiden on Vita, and Akiba Strip 2 and DW8XL. For $50 USD, that's a lot of import goodness to mess around with.
And unlike US PS+ which gives free games all at once, once a month, JPN PS+ seems to give new free games every week or two.
