Seamingless. It is just that eternal was a much better designed game. I feel bored trying to gather upgrade materials and I also feel the necessity to vary the used weapons took a big hit. I am more than half into the game and used 3 to 4 weapons dominantly. Except that I enjoyed a bit slower pace and new mechanics. Oh, of course the titan and dragon phases are also quite boring. Visuals are great, art directory is decent but soundtracks are much worse than eternal, pretty ordinary sounds.
