Arknights

But it's not worth

only share clues needed in reception. this is good thing than bad because everyone needs clues and people who got too much same clues can share between friends/players

Yes. but in meantime we can play in different modes like Intergrated strategies, SSS, paradox simulations which doesn't need any energy or any item to start mode

Yes. basic achievements are just do that XYZ times. reach XYZ level. just simple things. event badges require specific way to obtain that and it's fair enough. for example : do XY-12 stage letting boss go trought safe point. most of them are not challaning if you know mechanics and gameplay

Yes. between events or in the last days of event daily time spend on game can be no longer than 10 minutes (log in > base > shop for new items > annihilation stage (skipped because of special item) > make 3 requitments take a daily all rewards (or weekly if something is avaliable) > close game). as i said everything can take no more than 10 minutes to make basic daily activites

Yes. Why? because they don't push game into pay to win buisness strategy. everything is available without spending real money. game can be completed without using top tier (6 star) operators, even 4 or 5 star operators can handle stages or even make that more effiecently

only premium account. if i remember 5$ per month which is not giving too much

Yes. but it not waste my time. from current event there is option to repeat 6 times in a row one stage. this is QoL feature and you don't need to keep on eye phone/PC always

for new players it can be some kind never ending game. to read lore we need around 130h or even more if someone is not good in english. main story is long but optional, side stories are probably 3/4 of the game

But it's not mandatory
