Gamebreaking (apparently) aspects of UW I like.
1. Undemanding pace. Winter is Coming, but I have all year to get ready for this. Allied is this, generally have to look for trouble before finding it.
2. Palette, art style and music.
Other aspects I enjoy.
The setting, my favourite. Though I guess I would play in post-apocalyptic New York if I had to.
Graphics pixel or isometric, though could live with other options.
Thanks.
