Disgaea 4: A Promise Revisited was a popular JRPG title back in the early 10’s for the PlayStation 3 and even the PlayStation Vita. When it comes down to JRPG’s games it seems like Nintendo based consoles generally tend to miss out on very popular titles. In 2017, it seemed like a different story since Diseaga 5 was ported for the Nintendo Switch along with the PlayStation 4 back in the Spring of 2015.
In terms of quality Disgaea 4: A Promise Unforgotten may not have been on the same level as the PlayStation 3 port of the game. However, if Disgaea 4: A Promise Unforgotten was released exclusively for the Wii or the Wii-U the game could have easily been more attractive similar to how it was for Sony made game systems. But in terms of sales it would be hard to say whether or not that a Wii version of Diseaga 4 would have been a success or not. It’s quite possible that the game would have had more success as a Nintendo 3DS game.
