I don't own that many Nintendo 64 games, and even less that I can actually do playthroughs of.

Mortal Kombat 4

Playthrough with Quan Chi. This game is very easy to beat with him, as you can just spam his teleport stomp over and over, the CPU mostly won't block it. He also has a copy fatality, letting him use his opponent's finishing moves against them, so you'll get to see a variety of fatalities in this playthrough.

Playthrough with Smoke. Beating the game with Smoke is fairly easy since you can use the same jump back kick, teleport uppercut, spear, combo strat that worked in UMK3. Unlike in the PS1 version, Smoke's spear doesn't work on Motaro, it goes right through him. So you have to get a bit lucky when fighting him. My tactics are to do a neutral jump, and if he gets close, do a jumping high kick and then immediately follow it up with a double high kick combo, then keep doing this.

Another difference between the Nintendo 64 version and the PS1 version is how Smoke's spear works against Shao Khan. In the PS1 version, if Kahn gets dragged in by the smoke, he remains stunned for less than half a second, making the move near useless. However in the N64 version, the stun lasts a lot longer, making him very easy to beat.

I have done two playthroughs of this game, showing different levels and both endings. The true ending features an additional final boss, but overall this game is much easier that the SNES one.

The second playthrough uses the Wii U virtual console version of the game.

Star Wars Rogue Squadron

Difficulty level: 4 out of 5

The first game in the Rogue Squadron series was released in 1998, and was available for the PC and Nintendo 64. The Nintendo version is the worse of the two, mainly due to its poor frame rate. It was also among the first games to make use of the Nintendo 64's expansion pack, which I used for this playthrough.

This game gets really hard in places, it's much more difficult than the Gamecube sequels.
