If you have a good base collection you are fine. The rising tide lifts all boats. You can trade games in and out as you see fit. I am at personal capacity so a new game to me means something has to go. If you are new to the hobby it is getting harder to get your foot in the door. The nice thing is (at least for now) if you chose your games wisely you’re really not out anything other than your initial investment. I’ve collected for a long time and have only purchased 3 NIB and each title is now worth considerably more than I paid for it. Avoid titles like Thunderbirds and WWF and you’re looking pretty good these days.
