Ask (people) who have the game anything

This question might not fully relate to the Japanese version but:

I hear a lot about the lag in the game since there's no install data option and people leaving the game running for about 30 mins before starting to play. So I assume this is needed every time I boot up the game right? That's kinda unfortunate and not so fun.

Also is there any word from Aksys or Ghostlight about this issue? Is it going to be the same for us?

Just out of curiosity, is RoAW2 easier or harder to platinum? Because I was able to earn RoAW and RoAWZ platinum, but it took a long time especially for the titles trophy. Thanks!

How many costumes do each character have?

Regarding the gameplay and batte system.

Before I ask, I just want tto say, I'm in the process of obtaining the truth ending and therefore the platinum trophy in Cross Edge.
Now we've all heard about the difficulty on this game along with the learning wall required to play this game to the fullest.

With that said, I'm wondering if the gameplay of RoAW2 is in the same level of difficulty and challenge as Cross Edge? It's. not too important, but I did greatly welcome the difficulty in CE,, so I was hoping for some more brutality.

Now about the Battle System, sort of the same question as before, there's enemies in. CE, that in the point I'm at in the game, are destroying my party in one turn XD!!!!! Madness, and I love it, reminder of how much my party still has to go.
With that said, how far is this game from that level of difficulty.

Sorry, btw if my post is a mess and hard to read.

And thanks TC, the info that you provide is immensely appreciated, thanks for your time and effort, really .

Forgot to ask, how's this game in the fan service department?.
Now let me explain, my wife is not all that into Hentai, or by that extent, hates anything that it's intended for an Adult to grasp via images, dialogue etc. I guess what I'm trying to say is, that given my wife doesn't really like fan service, my question is

How much of this game will I have to play when she's doing activities of her own?. I know for a fact that the minigames will create some disputes, especially the bath tub one. In other words I just don't wanna make her mad, she's ok with me playing is just those few scenes that I'm worried about.

I have a question that has been bothering me:

I keep reading that this game does not take place in the same continuity as the others. How and why is this so?
