As a person who played all PB's previous games, I pre-ordered the Elex 2 and just finished it. Story is very good as in all PB's games. Love it. Performance was OK even with my below minimal hardware (RX580). Well, it took some time to find Graphic settings for comfortable frame rate/image quality. There were no critical glitches that affected the story (only Irissa quest was bugged, but patch came just in time).
Graphics does not look very modern at the beginning, but... We love Gothic not for its graphics, you know. Combat is hard when you low level and later becoming too easy. Story is good. A lot of places to search. Many interesting and funny quests. Summary: Gothic's fans must to buy it.
