I think it's pretty hard to predict the secondary market. Lili, on paper, is a bad investment for a reseller. That said it's fairly low print and it seems the very low print games are the ones that tend to have the most value. Sort of like Breach & Clear. With so many collecting for Vita it really limits how many possible complete collections there can be so the price goes up while there is demand. Similarly Retro City Rampage. Only the Vita version gained alot of value and that's partly due to being super low print. The PS4 version and the reprint haven't gained much at all.
To be fair, the PS4 RCR was well over $150 for quite some time. It was only after the reprint that it dropped in 'value'
