This thread is amazing. Thank you, guys, for doing this.
HellRogueBasically you wander the infinite procedurally generated plains of hell, encountering horrible monsters (think Dwarf Fortress PG demons) and rotting, abandoned areas - an urban city, a castle, a temple, half of an apartment building. You can find other damned souls and slowly, slowly become a demon yourself, as your body is torn into corruption and distortion. No real goal; you just wander into the wastelands and find terrible PG Beksiński things.
Would anyone play this one?
Fuck yes. As I read this, images of Beksinski and Barlowe ran through my mind, before I even saw you mention the former. Procedural hellbeasts would be The Best
Town Guard RL
You ain't an adventurer. Maybe you did that in your younger days but you've settled down, now. You are a member of the Town Guard. This is as much about fighting as it is about securing your social status in the town. I mean you could just do your job and nothing more - rid Granny Rowe's basement of giant rats, stop the summoning of a demon in the local church, assist the occasional adventurer on a small portion of his or her journey, or help them through a mission commissioned by the town itself - but if that's all you do, you'll be seen as the distant creepy guy who has no friends and takes his work too seriously. Lighten up. Have some drinks. Get to know the town. I mean you've got to protect these people, so cherish them while you can, because once they're gone they're gone for good. Granny Rowe won't bake you cookies if she don't know you, but she can't if she's dead either. Town might grow, but slowly. Not so quickly that every death will be immediately replaced by another life. Slowly enough that if you fail a mission too badly and too many people fall, the place will seem empty for quite a while. Get to know a local lady, if you like. Court her and get married. And stay on the good side of your fellow town guards - more than merely attacking you, they can make your life a hell should you prove yourself disloyal or untrustworthy. After all, you are not a hero.
You can choose to play in a large or small town, and anything in between - large towns are bustling with foreigners, traders, heroes, and underground societies. It will be impossible to get to know everyone personally. Small towns are quieter and slower, with generally smaller problems (though they're usually the first to be targeted by Evil Wizard Conquest Regimes and such). You can get to know everyone if you try hard enough.
