I believe this game has tons of potential, so I'm going to give my straight forward opinions, in hope this game goes in a direction that I consider "revolutionary". This is the first one..

"Free Roaming Mode"

The ability to easily go anywhere, at any time, and do what you like.
A little more in depth than that.

The "Story" aspect of this game is what I feel is going to hold this game back... Because I feel like the development team is looking to create a world full of girls that you have a story with, and each is tied to a specific location (Gym, resort, school, etc). This is going to make for a very RESTRICTED and traditional game, as it is exactly what they do in most sex and hentai games, and that's exactly why most sex/hentai games fail, because that is utterly, utterly unrealistic.

Allow me to go to a place, like a gym, where there's more than one girl that I can approach.
Then have the "story" elements come to the user. Like, one of the girls stands a chance of randomly bumping into you at the gym, and triggering a story chain.

I, however, DO NOT, want to be held back by ANY sort of linear story content.
The ability to unlock free sex mode isn't enough for me to sit through a sex game with a linear story, based on me acting out the life of a imaginary dude. (getting to work on time... Going to bed... Finding my car keys...)

Good point, I fully agree and I believe this is already the direction they want to go to but not in the near future.

This is what I imagined the story mode to end up being.

A free roam without effort is utterly boring. It needs a lot of content. Planned content. As long as the stories leave room for player-decisions, we should be good.

Adding the ability to go anywhere as you please in the game's current state would be a fun addition to fast-sex mode, but it'd be useless elsewhere without a lot of work. Sadly, with a small team, just a little bit of work takes a long time. I've got faith in them though, considering what they've already made.

I do wish the fast sex option would allow us to choose the room and the girl. That one restriction is a sad one for me. Hopefully the new version will have more options.

They had mentioned by version 9.0 on the off-beatr project page that there would be a story that allowed for multiple stories to play at once, but that really doesn't sit well with me as far as having an open ended world, such as, if I can't have the tentacle monster in the swimming pool by some random event. To be honest, the current story setup does worry me. If I have to exit from the bondage game to get to the classroom game with a different set of characters, the immersion is going to die for me. If the story modules are linked and shared within the same game world then that would be a little better. I think it would just be best to have any girl in any situation though, where the stories aren't limited to one or two girls in every case for a given scenario. Have the game objects' relationships to stories be dynamic.
