btw is it just me, or is One Piece: Pirate Warriors 3 (on PS3) having decent legs for a Warriors game?
No, it's not you, the game is selling well and in the long period.
Tie ratio is actually 58,07%
But there are also other games showing some legs, and they have been released in the same day OPPW3 was released, the (in)famous March 26 (famous cause a lot of games were released and infamous cause a lot of them bombed)
Pro Baseball Spirits 2015 was also released on March 36 and both versions are still holding the chart (Famitsu numbers as usual), and they have a good tie ratio (61,52% PS3, 59,13% PSV, the latter is performing better than last year and actually it's the best result for the franchise on PSV)
Sword Art Online Lost Song, Vita version, despite a higher tie-ratio (72,69%) after one month and a half has not left the chart yet
Lego City Undercover (3DS) thanks to the GW re-entered the chart and it has one of the lowest tie-ratio : 29,80%
Last title I want to mention is Assassination Classroom, tie-ratio 36,23% which could have been more less if it hadn't stock problems after it's release
Of course titles for Nintendo platforms are common to have long legs (as I pointed out last week, iirc), so that bunch of games for PS3 and PSV mentioned above are really doing good
