I don't think I could say never but TZ is not going anywhere for a very long time. Best game ever. Love everything about it. Mine was pretty nice when I got it but needed a lot of work to get it playing right and looking like I wanted. Congo would also be very hard to let go. I put a ton of work in mine just getting it playable. Just a fun game to play as long as you don't take it too seriously. Love the goofy theme and layout.
