Q.? Already having the TSW Base Game, If you Buy the TSW 2020 Collectors Edition when you upload it to your PS4 will it simply just add all the extra content / routes etc.. and will all data, trophies earned thus far in the Base Game be kept or will it mean starting the Game again from the very Beginning ? ie: will uploading the Collectors Edition Disc overwrite the Base Game. Apologises if this has been asked before Cheers.
It should all carry over. The base game is exactly the same, but what you're buying is a bundle of that base game and various DLC routes. Are you sure that's the most cost-effective way to get the routes you want, though? Deluxe Edition and most of the DLC is currently in the PSN January Sale - see this page for all the current pricing.
