in unassisted runs, tool-assisted speedruns often make much heavier use of them. This may in part be because the majority of glitches are very difficult to exploit without frame precision and re-recording. In some cases, a trick relies not only on precise timing but also on several variables in memory having a specific state, which would be nearly impossible to recreate in real-time and without detailed knowledge of the game program. Entertainment factor These differences also lead to different expectations from tool-assisted and unassisted speedruns. Taking damage when doing so does not save time and/or is not required may look sloppy in a tool-assisted run, while being hit by the occasional hard-to-avoid enemy in a relatively long unassisted speedrun would not prevent the runner from holding their world record title. After the advent of frame-advance, frame-precise movement has also come to be expected, the lack of which may be characterized as sloppy play. Another difference is in the standards of use of waiting time in the speedrun: in situations where it is not possible to make the game move faster, and the player has to wait, such as in autoscrolling or any other areas of a game in which the runner does not have control over the speed, the runner is advised in TASVideos guidelines to do something entertaining for the viewers. An example of this is the gathering of 99 extra lives in the autoscrolling sections of the famous Super Mario Bros. 3 speedrun. In unassisted runs, players usually would not risk dying and having to start over to entertain the viewer. Runs that prove unentertaining may get rejected for publication, even if the run itself is technically optimized. A bad game choice may contribute to a lack of entertainment. In this context, a "bad game" may represent a goal choice that does not demonstrate the merits of tool assistance, so choosing a different goal may alleviate this issue. In other cases, such as the Excitebike TAS by Thomas Seufert, a previously unpopular game had achieved a notable entertainment boost due to massive improvements brought into play by increased tool-assisted precision.
