Neo Scavenger is immmersive. Non-linear. There are competing choices that make sense. Challenging but not discouraging. The crafting recipes are interesting. Combat requires thought. Poor decisions lead to poor results. You can fall into a role. Starting options make it replayable.
There are rare almost-random events that can cause death with no posibility of escape. It seems that, after the first hour or so of a new character, a careful newish player can run a character without dying at one of these events. So far, it's fine with me.
In 2019, on a 32-bit Ubuntu-based OS, it just works. No tinkering required. Neo Scavenger uses Adobe's Flash, which I've read may cause some older computers and operating systems to work pretty hard. Flash was a design mistake now acknowledged by the creator, but it doesn't matter if you have a modern desktop system.
New Scavenger will be a classic. Do you like turn based roguelikes? Then if you don't have this game in your gaming experience, you have missed something significant. Even if there are reviews here that make you doubt, you should try it!
