Went through world 8 today. Some good stuff in there. I think 8-7 with the dinobone coasters is my favorite level in the game. Was really neat. I like how the boss fights in the last few worlds really tried to change things up. World 7-8 were kinda hard going for 100% completion. I got to world 7 with 65 lives and finished the game with 35 :'( While I love that the game was actually challenging, it's a love/hate thing because it's been a while since I've played a game that makes me want to throw my wiimote in frustration over and over. I hated 7-6 with the flying beetles. Oh god did I hate that. Also any level with wii gimmicks, definitely hated those. Not sure if I want to try world 9 today as I think I've had my cup of tea of dying for today.
I think while NSMB Wii has been a great, great game. I enjoyed it less than the other marios because in those games I wasn't worrying about finding all the big gold coins and wasn't jumping into every wall and searching every cliff for them. I was just running through the levels enjoying them. Going 1 level at a time here getting all 3 coins before moving to the next, the game was a mix of fun (discovering the coins!) and frustration (dying and redoing the section over and over until you have them all in one go!). I think I like Mario better when you are just focusing on what's in front of you to get to the end of the level. I could have just not gotten all the coins, but I have collectathon ADD in games and if there are things to collect I feel like I must 100% them all.
Will try world 9 tomorrow.
