I mean I have continually played games during my academic studies and I can honestly say that playing in moderation helps. The jump from GCSE>A-level requires you to be able to balance work and play (you really need something to vent into during AS imo). I would not bother giving up something you "truly love" for academia.
I managed to get A/A* grades while playing in moderation, the only downside to moderation is that I deranked from global elite on Counter strike.
Tl;dr: Continue playing games in moderation as it will be a good stress outlet while you study.
