This game is on the list of best games ever! It is filthy, violent for its time, and infamous for being extremely hard on some levels. It took me three weeks to beat this gem of a game because of hard levels especially toward the end of the game. Some are harder then others while some are easier but not by much. The levels that gave me a hard time in no particular order are the surfing,(Mugged)Matrix, (Heist) The little girl/Teddi robot boss (I don't know what it is called but it took me several tries)The Club level, (Just because of aiming and the fact that the rock dudes don't like to be pissed on) The final boss. (This took me MANY tries, a lot of game overs, and patience) The rest of them are more annoying and frustrating then hard. The game is simple but complex in beating it. This is one of my favorites, the other being Madworld. Seriously the game is hard but despite a shaky (sad) ending, it is well worth playing and I don't believe that you can master the game or get bored of it. You can get stuck but that is about it. This is WELL worth the Viz to play but what I notice is that the Viz version skips around a bit. Instead of waiting to die to meet Gregg, it happens right after you get the key in the training level. Anyway, please let me know what gave you stress in this game and if you ever got through it.

I actually never played the on the N64. I have Conker Reloaded for Xbox. This is actually the exact same game with better graphics and a few added scenes, so it really is no different. Anyway, I honestly did not find this to be a difficult or frustrating game. The first time I played through it, I get through the game without losing all my lives. Now, I can get through it without losing a life. However, I usually die once on purpose because I love that scene with the Grim Reaper and how he complains about how much he hates cats. It is hilarious. But if I had to pick a part of the game as the hardest part of the game, I would pick part where you are swimming in a metal tunnel and sharp fan blades. That is only because the swimming controls are a little choppy and took a little while to get used to in order to not touch the fan blades, which is instant death. 

I Think It's Either the Flame Guys Boss Level, Trying to Get Past the Spinning Blades Underwater, or the Final Boss Fight.
