Literally nothing wrong with using cheat engine for speedhack in offline games. Way too many games are just fucking slow or purposely waste time to pad the game.
I use it in many, many games and it smoothens the experience a lot, especially when slow movement speed and backtracking are involved (hi there Underrail)
No longer Underrail responds "hi" in this case but it did, for a very long time, most of its existence in fact. Slow walking movement that is. I never understood the accusation of backtracking in this game. It isn't worse then in many other games, including some classics praised on this site. Games that aren't accused of it.
I have a theory about it. This is actually a problem of
rubbish graphics of Unhderrail, not
backtracking. Time simply "goes faster", subjectively, when you have nice views to look at instead of poorly drawn, empty, samey caves
half most of the time.
In general i agree, using cheats to make game go faster when it doesn't change the gameplay in any other way is a good use of cheats. Wizardry 8 was only playable because of Wizfast for example. Having said that, i don't remember using cheats for the last several years.
