World didn't have to contend with the impact of covid on development, Rise did, hence true ending being added a couple of months after launch and its roadmap being somewhat sparse.
As for Rise only having 60-70 hours of content, I've played over 90 hours of it and I still haven't built even half the armor sets and even with sticking to just 3 of the 14 weapon classes I still haven't built everything in those classes.
Also, base Rise has more monsters than base World.
the point of monster I Agree. and the point of covid, you are right.
