I played Elex for about 50h - 60h and this is my thoughts:
Tech
a) Elex is very stable game. I haven`t have any CTD so far.
b) Loading of savegame and saving are very fast.
c) I didn`t have decrease in performance of game even once.
d) There are not loading screens during exploration.
e) My computer is not new but Elex work like a charm.
f) You can name your savegames.
g) There aren`t items cliping in Elex
Game - general
a) Exploration of the world is super. You will find something interesting in every part of the game world.
b) Map is huge. After 50h-60h I explore Edan (80%) and some of Abessa (30%).
c) Loot is hand placed and don`t respawn.
d) Strong enemies ( monsters and humans) don`t respawn. Weak enemies but not weak humans respawn afert some time but you can take skill/perk to stop them from attacking you.
e) You can learn history of the game world from people, holodisks and books/letters
f) There are not level scaling so you must take care during exploration of the map.
Game - quest
a) In Elex most quest have more than one ending and player can choose which one he wants.
b) In quest and dialogs you can use your skill ( there are 4 - combat etc) to earn exp, money and items.
Game - economy
a) Money (elexit) is very important in Elex. You can use money to buy items, weapons, armours, training but most important is using money to buy alchemy components. Alchemy skill gives you possibility to make strong elex potion ( + 1 sill point) and elex potion (+2 attribute) . To make S.E.P. you need about 1000 elexit for component and for E. P. you need about 500 elexit. Skills like Haggler (reduce prices) are very useful and skills to generate money like pickpocket and animal trophies are very good choice too.
b) Most items, if you buy item from trader, appears again in trader inventory but not all
Game - combat
a) Combat could be better but is IMHO ok.
b) Eniemies are deadly and can kill you very fast if you underestimate them.
Game - NPC
a) Most people looks very similar and all women look the same
b) There are very few lectors
Game - skills
a) Skill (combat, survival, personality) are very important and gives you new possibilities.
b) Creation skills (alchemy etc) can make you game more interesting, easier and better.
