most models and textures are straight from the GC game.
Mario, water and lighting looks next gen. Obviously it will look weird when you combine them all.

lol, I'm not joking. A remake by Nintendo would obviously look better and have more vibrant colors. I was just saying that I would like to see a SMS remake in UE4.

I think it's the lighting; I noticed it a lot in UE4 fan remakes.

Most visual tech tends to be overused when it's new. The lighting here is overdone, and the contrast is too high; lighted areas are almost white.

Same can be seen here. In an attempt to be cost effective, they took their up-res'd Gamecube assets and applied lighting and shadows to the entire world (VS just the character models like on GC). Personally, I think they overdid it (devs + new tech).

Another example. It hurts my eyes ._.

Moral of the story: tone down the lighting and shadow effects, pls.

It's not overused, these people are just using out-of-box settings and assets.  90% of the time you have these people using the default lighting and often prepackaged or purchasable assets plus assets ripped straight from the games.  It's painfully obvious here they are using mostly ripped assets from the GameCube release without doing anything to make them work well with the lighting and rendering features of UE4.

So how long before it gets taken down?

I didn't mean overused as in 'the number of games using it', but rather how it can be over-applied when it is used.

Like applying a saturation filter, VS over-applying it:

That's not bad, but I swear people are just putting old assets into new engines to get attention. Everything looks more impressive when you put it in a more advanced engine, even if almost everything is exactly the same. This seems to be the case here.

My point was that these people aren't over applying effects intentionally to look impressive, they are just plopping assets in engine.  This is just the default lighting setup with no changes, as is almost always the case cause most of these people never bother to learn how to edit lighting.  

It looks fine when you consider it's likely 1 or 2 kids doing the whole demo. An actual game would have 60-100 people working on it.
