Having recently come across a fair amount of Philips Videopac games I was wondering if anyone here knows what kind of rarity and value they hold, if any.

The only real rarity guide I have come across so far dates back to 2006, and I guess a lot has happened since then. Having checked around on various other Videopac sites, this seems to be the general problem, the lists are horribly outdated (Or have nothing changed for the past 5 years, or are certain games still going for £100?).

I'm hoping to find out if it's really worth trying to collect for, or if I should sell them off to help fund other parts of my collection.
