I remember playing new games and from what I recall they had some pretty glossy surfaces; perhaps not like the super-buffed auto clear shiny that I see on restorations, but shiny nonetheless... I've been clearing my games with acrylic lacquer and that is some fairly glossy stuff; I believe that's what games were being cleared with back in the day, but who knows...
You can always change it up after the fact, so go with your gut!
