Barely gave it 45min for now; wish I had more. This is right for you if you liked AER and wished it was longer - It certainly looked like it would - and loved the art direction of Kenshi, but found that too grim and demanding after a long day. Among the more recent games, some comparison might be drawn with A Short Hike in terms of gameplay style, given what I've seen thus far. Story's also good with nice characterizations. Hope it'd stay this way to the end.
...Especially for an experience that one cannot expect to replicate in real life anytime soon if ever, given the circumstances. But yes, it was a fun little experience, one that felt somewhat short but not detractively so - Though it did feel tied up somewhat too soon, maybe to keep the scope in check. There is some railroading at places - not unexpected given it's largely a story of rail travel, and again not too distracting. Treat it like a paperback novel with pop-up inserts, and have a good time.
