I'm one of like 3 people that hate that they removed the optional filter to make the game look even more depressing and shitty when playing TLAD
TLAD is supposed to be on the complete utter bottom of Liberty City
With Niko you see him crawl his way out of that tier of the city and get to the "Lower high tier" upper parts of LC where as TBOGT is almost entirely set in the rich highlife parts of the City outside of when Luis visits his mother and old friends that are still stuck there.
In TLAD Johnny basically never gets out of being a fucking rat living in the bottom of the entire cesspool.
Even when you beat the game your entire local chapter is destroyed, the club house gutted then burnt down, almost all of Johnny's contacts/associates (outside of a core few Lost gang members that remained loyal and alive) are dead or in prison and Johnny lives in a complete shithole dilapidated abandoned drug den that wouldn't look out of place in Manhunt.
