Anarchy Reigns is worth more than its super cheap price.
Regarding game length and repeatability, I wish any game that was arguably short featured a random element to keep things perpetually fresh. World and hazard generators are are of my favorites, and item dropping is pretty ubiquitous - all of which are combined in FTL to make it the best Oregon Trail in Space and my favorite rougelike. If not randomized levels, then maybe branching paths?
I'm a gameplay person, meaning the story, setting, characters, whatever take a back seat to the intrinsic enjoyment found from what happens when you move the control stick and press buttons. The other stuff can be awesome and support and motivate you, but I'm generally not interested in the others if the gameplay isn't there. When things are randomized, I feel like the game had essentially reached infinite replayability.
