A blessing in disguise (A backlog story)

Hey guys, so I have a 2TB Hardrive in my PS4, almost every Flash sale, temptation got the best of me and bought a game, after that months later I haven't touched that particular game and the game now is even cheaper or goes for free in PSPlus. Problem is that 1.- Don't have enough time. 2.- I tend to trophy hunt most of the games, so that means it takes me longer to finish 1 game.

Then It happened last tuesday while I was downloading the free games. "Error, not enough space to download game" I uninstalled 2 disc games, so Bloodborne and Ratchet and Clank are now on my library ready to play, then a super surprise flash sale, since most the time those are in the third weekend, I saw some games, I was interested in some, and it hit me, "I don't have enough space to download play and finish this game". Now I need to play and finish some digital games before I even attempt to install a new one or buy another game.

My initial strategy is to go and finish the easy and fast platinums, problem is those games are super small, but even at that it will help to get some space cleared out before playing a big but not long enough game.

What would you do in my case? I for one think this might be a good thing to just play the games that I have and not fall into spending more money in games that I might not play soon enough.
