I bought a PS4 earlier this year, and bought Grand Kingdom shortly thereafter.
I had a lot of trouble getting into it, for some reason. I'd play it for an hour or so at a time, but it didn't really grab my attention so I moved on to other things.
This weekend, though, I was in the mood for a SRPG so I thought I'd give it another try. Unfortunately, same thing--I'd play it for an hour here and there, but it I kept putting it down to do other things.
But, this time, I kept at it. And now I'm really loving the game (played six hours straight after getting home from work yesterday, LOL).
I think part of the problem is that the game's systems work a bit differently from many other games, and it hits you with *all* of them in a very short period of time. So, there's a lot to get your head around. Once you start to understand how all of the pieces interact, though, it starts to get a lot more fun.
There's a good variety of classes, and since all units are randomly generated, it gives you a lot of incentive to keep going back to the recruitment office and look for that perfect unit to add to your team.
There's a not a huge variety of enemies (seemingly), but the game does do a good job of at least mixing them up in different ways (fighting a team of all blacksmiths is *very* different from fighting a team composed of a blacksmith, a fighter, a couple of witches, and a dragon mage). The game also keeps tossing in different environmental effects (like disabling blocking, speeding up enemy actions, putting in various traps and barricades between your team and your opponents) that contribute to combat variety.
I wasn't sure I would like the partly turn-based, partly real-time combat, but it's definitely fun. I've seen some folks claim that it keeps you more engaged than a purely turn-based would, and there may be some merit to that.
