This is an ingenious pair of games, and I'm very happy to have played them. The mechanics of Polaris were more appealing than HWC, but even this made sense within its own context. Excellent choice of music in both (you may also like the McCarricks (
http://www.houseofmccarrick.com/ ) and Cinephile (
http://www.cinephileonline.com/ ) at a guess). If all art aspires towards the condition of music, then your mod is halfway there with the effective selections you've included.
It's inspiring to see interactive narrative finally embracing its medium and becoming more than a point and click adventure - the obvious comparison is Dear Esther, but where that was grand and ponderous this is sharp and witty, (we needn't mention Korsakovia). The spoken dialogue really made HWC come alive for me, though I recognise how time consuming it is to do and understand your aversion to doing that again.
There are several things here that are interesting - the first is that there is no "good" ending. I discovered all 3 endings in Polaris and all 4 in HWC, and found each to be as valid as any other. As has been discussed at length, games traditionally present the world in black and white, victory or loss, and so it's great to see the true ambiguity of life come through, and more effectively than in larger works which pretend to do much more.
The homosexuality issue didn't occur to me as an issue while I played it - I read both as being about love and relationships. I found both to be sweet and sad, (Polaris especially reminded me of certain parts of the novel The Rules of Attraction - not the film). It didn't strike me until I read this forum thread what an issue the identity of the player character would be. You've used a medium - not just games, but mods of games - whose base demographic won't have sympathy or experience with the themes you've chosen. It's like writing show tunes for Menonites.
It's great to see, and I'll be watching closely. Please let me know if there's anything I can do to help.
