Do we have any real choices in the game regarding storyline and girls to choose n deny from?
Per the Developer Notes on the OP, there will be a few girls who are optional, but most will not be. The choices will be more in line with the intensity or type of relationship than whether the MC claims them as his or not.
Storyline choices may have some effect, but they're not going to have huge entire-storyline-branching divergence, since that multiplies the work the dev has to perform drastically.
Many people do not share this opinion. Also, Aoife is a primary LI, so if you don't like her, this may not be the game for you.
and will kes keep on bitching about her dead family n friends like boofuckingoh .
Kes is one of the MC's party mates, so the MC bringing her out of her shell and helping her through her trauma will likely be a major component of her LI arc.
Fundamentally, if you're looking for a quick fuck with no story and no emotional connection between the MC and the girls, this will not be a good game for you.
