Apparently it wasn't a problem to achieve this 25 years ago, and it has only become exponentially easier to achieve since. Aside from this gameplay being the very medium of the game, this is not just "they put in a little less effort" it's "how in the hell does this happen". Maybe you're not understanding the sheer magnitude of difference here. Are you telling me that a single person who has only dabbled in Sonic for a couple years, not even 20 years old, can produce this in two days time at a minimum of effort, whereas teams of professional developers who have invested their lives in Sonic for over a decade and have had multiple opportunities of years long projects and million dollar budgets, just can't be arsed to do it. Why put in the effort even though it should in theory be even faster and easier for them to accomplish than Tpot and then some by a landslide. None of that makes any sense.
