The problem I have with believing any guide to be rare is that the first print run is in the tens of thousands

The Fallout 3 GOTY CE Guide for instance used to sell for 50 - 70 USD mint but due to so many coming back on the market recently from ppl seeing the prices, a mint copy goes for 20 - 30 USD

The Fallout 3 GOTY CE Guide has a print run of at least 40,000 which for a CE might be on the lower end but for a CE guide? Plenty of copies

I suggest you wait and watch the market for a while to get a feel for what any particular guide is truly worth

The Zelda Phantom Hourglass CE guide used to sell sealed for 75 - 100 USD but now goes for 30 - 45 USD or so

HTF guides are Bayonetta and the killzones solely because the only English versions were distributed in the UK and maybe Aus/NZ

So their print runs are probably smaller but still in the tens of thousands for sure
