I actually re-thought out the idea of realism not too long after i posted that, primarily for the fact that there is FPS games made to incorporate realism. Red Orchestra 2 is praised for it, but at the same time is a complete push away for people because it has been referred to as "too realistic". So sure, there is some games out there like that.
But again, gaming isn't about the graphics, it is about enjoyment. The one thing that has always annoyed me, and it did so even at high school, was how people refused to play games because they thought the graphics where bad. Yet the game(s) they refer to are probably some of the best things to hit consoles at the time. I admit, seeing a game look lush is fantastic, Batman and Skyrim can be jaw-droppingly gorgeous with their attention to detail and skydomes, but again, that wasn't what pulled me in, and i doubt that would ever be what would for me. But yeah, i always did think like that, hah.
Pulling myself back to Pokemon x Nobunaga's Ambition(one day i will just write it out one way, not two different). I'm not sure how many games in the Final Fantasy series you've played, considering that if memory serves, only...3? Main series games are turn based(I, III and X, could be wrong with III, haven't played it in a while). The rest are time based. Tactics is turn based yeah, but that is outside the main series and tries new things. Crystal Chronicles is all real time. I guess my point is, if you're looking for a "turn based game where you fight monsters" FF isn't exactly the best series to look to. Specially with the direction XIII, XIII-2, Versus and Type-0 have taken it, as well as XII. Breath of Fire may suit that idea better.
Regardless, Erm. With the game. You don't choose who your pokemon is from every single one available. Each character seems to have one associated with him/her. Oichi has Jigglypuff for example, Oda Nobunaga has someone i don't recognise, and the main character, whether you choose male of female, looks to get Eevee. That's going by the trailer anyways. In terms of gameplay, we can see it's an Turn-based Strat. How it'll work, hard to say. I need to find a video focused on the gameplay itself to make a proper judgement on that. But i expect it'll work like most, or possibly Nobunaga's Ambition itself. Though i need someone to tell me what that is actually like.
