Alien Trilogy Dos
But Slumberland is an unexpectedly dangerous place, and the game's advanced difficulty level no doubt took some unsuspecting youngsters by surprise. Gorillas, lizards, frogs and other feral friends can be temporarily tamed when Nemo feeds them candy (do not try this at home), at which points he saddles them up Yoshi-style, allowing him to reach new areas.
This is a list of games that do not run properly in some ways on CPUs faster than what was common than at the game's release. 1990+ for the most part, since before that, this was more often the case than not: As a general rule, games for IBM XT computers require a 8088 4.77 MHz to play right.

Some CPUs, for example AMD K6-2 and earlier Pentium IIs have selectable multipliers, which may help with achieving the lower speeds recommended for some of the games in this article. Additionally, disabling L1/L2 caches will slow down the processor as well, e.g. a Pentium III with disabled caches will be comparable to a 386. Setmul is a software utility by forum member gerwin that allows multipliers and caches to be changed/disabled and enabled without a reboot. For certain P54C Pentiums, it also allows manipulating Test Register options for further speed control.
Also, it is possible to use a slow 3D card to slow some of the games down, especially with the early proprietary APIs; a special case here are Rendition Vérité cards, since their slow VGA performance will also bottleneck DOS games using these modes. Finally, as a last resort one may try slowdown utilities such as CPU Killer and Mo'Slo.
For games with unlisted CPU specs refer to the requirements published by the developers.
