I don't feel the spark.
When I first saw Ion, that moving shot gave me such Deus Ex vibes that it sent a shiver down my spine. Technically, this game is head and shoulders above Once in a Lifetime. And the game within a game concept is so very promising.
Yet I find myself hard pressed to care about any character in the between-game space (in Eternum 0.2 but outside Eternum VR) except Luna, mainly due to her mysterious power. They just feel so banal.
Mine is clearly a minority opinion, and I don't really know how to make the character interesting like in OIL and this other game I have been playing. I do think shortening the plot before MC goes into Eternum and making the MC less intrusive (I find him annoying) would ultimately make the game better, especially for players who want to try it out first.
