Mario Party 8 graphics are mediocre because really the game wasn't meant to be on a Wii. Hell, the debug menu is based on the Gamecube controller. I think that they did a bad execution there because they knew the GC was dying out therefore they slapped MP8 on the Wii.
The motion controls will make you want to kill someone. I never had a problem with the infamous "Flip the Chimp" but I understood how the game's motion controls can become unresponsive. Also, there are so many taken from MP6 and MP7 files that they never deleted so its in the game's memory. We can just say that this game was not meant for the Wii.
The Board Maps are indeed dull and I can't stand them... Bowser's Orbit w/e the hell sucks so much ass as well! I'll give props by saying King Boo's board map was the one that had me planning and I felt was the most unique in that it requires strategy. Goomba's board map was just RIDICULOUSLY long and free stars will kill anyone's mood. You need not to win minigames and you can have around 10 stars once again free of cost. Overall each board map is very boring and competes with MP1 for the lackluster board maps (At least MP1 had a reason though #Noshade).
The candies ANNOYED THE F*** out of me! There were only a few and I found myself always buying Thrice or Slowgo. All of the other candies I don't mind but it renders useless and then the board maps make the cheap items broken. CashZap Candy was ridiculous in how anyone can get it randomly. They needed an over-abundance of items for the mechanic they were employing. MP7 was alright with the amount of orbs b/c of the mechanical basis of Orbs but the Candies involved another mechanical basis therefore needing more candies.
Story mode... let's not even talk about how dubious it is...
The mini-games, some were fun, some were torturous, and others were just "Get it over with". I like how the did the endings and beginnings to make it a bit more interactively approached but the minigames weren't necessarily my favorite either. I DID NOT LIKE how the Duel Minigames contained about 2/3'ths 4 player and Battle minigames. I just found that haphazardly lazy (Now I don't mind it if it was split but you compare the number of ACTUAL Duel Minigames to the total to get the percentage and then come back to me with a conclusion). The gimmicks in the minigames (Mostly carnival attired) fitted the theme but I found them to be bleh as well...
Spaces arrangement were so boring... always finding yourself landing on a Blue Space. DK Space / Bowser Space were minimalistic and really didn't help the person who landed on it unless its at a right position or if you were playing a certain stage. 9 times out of 10 you find yourself helping someone else when you land on the spaces. Only Board Map that I found cool with this is the King Boo one.
Choose another Mario Party to play basically, this s*** will have you put on the "Really b****" face!
