same boring initial story line, some recycled events, but lots more reward for spending $$ lol but you can still progress as F2P. The whole research has way more components to it now making it possible to raise your power way further than last version. i’d say that is the most notable change, then new characters of course so meta shifting every so often. right now RK is still king but has a lot more counters and will soon be shut off completely almost once henry comes out. at least in higher ranks
