You know, there was a lot for me to hate in world 4. Especially when I had one last blasted token left. I strongly encourage you guys to use the Hunter tonic on World 4 if you're in a similar boat!
I really enjoyed most of Capital Cashino (except that blasted Hurdle Hijinx - still haven't even passed it yet! And the mine cart bit was frustrating too, I passed the track eventually but have yet to pass the next bit...those are the only 3 Pagies I have left in that level), I thought it was where the game first started to really feel like a Banjo game (and then they really finally hit that mark with world 5). I had fun finding all the hidden tokens, enjoyed most of the games you had to play to win tokens, and loved earning the tokens as the air taxi service. I liked that I actually had to go searching for a few of the Quills in this level because some were actually hidden whereas in earlier levels finding all the Quills felt way too easy. I even found
Plus working as an events technician one of the main venues I used to spend a lot of time working in was a huge casino complex, so I LOVED how right Playtonic got the look of this level - the gaudy patterned carpet (I cracked up laughing when one of the pigs mentioned he was admiring the carpet), the tacky Egyptian decor and fake palm trees and the gold drape, the hideous huge chandeliers, the glitzy gold and black marble fountain, all the flashing lights - they got it SO right it almost felt like I was at work.
Edited to add: Just something trivial but which shows the level of detail and thought put into this level - I thought I'd take a closer look at those hieroglyphics on the casino walls and as I suspected they weren't just random symbols but rather they repeated all around the walls "PLAYTONYCGAMES" [sic] on the first line and "YOOKALAYLEE" on the second line. (Might have been spelled "PLAYTONYC" on purpose, but I suspect they've accidentally used the double reed symbol for "Y" instead of the single reed symbol that can be either "I" or "E").
Edited further: I beat the World 4 boss and then passed Hurdle Hijinx for the first time both within 10 minutes of each other today, and then finally beat the high score after playing sooooo many times! Anyone got any ideas what I.N.E.P.T. stands for? I think "I never enjoyed playing that" is fitting for that boss. I now have 140 out of 145 Pagies and I think those four were the hardest of all (plus that timed tunnel you have to slide down in Hivory Towers was really hard too!).
