Well Hrvoje,if it wasn't for Rockstar,no GTA games would have been released at all,and sometimes,the game developers actually have reasons to remove extra features on those games.Sony Computer Entertainment made an agreement with Rockstar Gamers,which stated that all the GTAs would be first released for the PlayStation2,a game console that poses limitations not posed by modern PCs,and due to that,the developers had to remove a few things here and there so the game would work correctly on that system,and after that,it is modified just a bit to work on other consoles and PCs.GTA SA is the game with most removed content,it was going to be released in 2 discs,however,the developers decided to release it in just one disc,which explains why so much stuff has been removed.The original strategy guide for SA stated that it would have more than 400 different vehicles and more than 100 weapons,and the vehicles and weapons found in that game doesn't even reach the half of the half of these numbers!I assume the developers didn't even begin work on all of these.Also in SA,you would have to hotwire the engine of the car you would steal,but it was removed due to flaws in the PS2's hardware ,and then,when ported to other systems,GTA SA was still the same it was on the PS2,and the removed stuff just for that system wasn't introduced on other systems too,maybe because the developers had lost all of their work,and they didn't want to do it all again,or maybe they forgot to re-add them.
Sometimes they remove extra features because they are glitchy,and/or make the game crash.Most often a game struggles to meet a deadline,and by then,by all means the game must be finished and ready to go,and in order to that happen,they scrap the game features they were currently working on,leaving the game only with the things they finished working on.Anyways,I have to agree that the number of scrapped features in these games is way too big,specially in SA,and it would be really nice to have them,but unfortunately,the developers removed them due to issues,or they just changed the existing and made it look different,the SWAT guys for example.Having beta the beta versions would be really rad,I have toa dmit that,but we will have to wait to see if some beta game is gonna show up...
