About 10 hours into P3, and I have to say, by comparison, the criticisms of P5 restricting your activities are on the fucking money. In P3, you can do an afternoon activity, an evening activity, and THEN still study as long as you're not tired. No cat cock blocking you from doing shit.
Also, there are only three social stats to increase in P3 compared to 5 in P5.
Restricting your activities so much was dumb. This was a huge fuck up game design wise; it's not fun and adds nothing.
There are a shit ton of real quality of life improvements, tho. Fast travel, for one...
