@everyone - I think everything should be added now! Shadow of Mordor GOTY is on my list to fix. We've discussed the Halo collection before and opted to not include the additional items added post-release...for now.

Ori: The Collection - switch

Core Keeper https://store.steampowered.com/app/1621690/Core_Keeper/

@everyone - Those have all been added, except Ori: The Collection. That one had popped up before, but I'm not too familiar with it. Here's what I had posted:

I'm not 100% clear on Ori: The Collection, it seems as though includes the original Ori and the Blind Forest and the Definitive Edition...but one is a download code (which we typically don't include in compilations). Anyone have any clarity on this?

Regarding the title "Ori The Collection", it includes both games in the series on a single cartridge ("Ori & the Blind Forest" and "Ori & the Will of the Wisps"). It would seem that the version of Blind Forest in this collection is the definitive version - as many sites list it as being the definitive version... yet, there are some sites that don't list it as the definitive version - so this seems a little unclear to me. On a side note, it does come with download codes (but those are only for the two soundtracks). I'm not sure if this provides the clarity you were seeking, but perhaps someone who owns the game for Switch can confirm if the included first game is the definitive version or not?

@MightyCrow - Those have all been added, except for the Klonoa compilation. I've been trying to figure out which version of the original game is going to be included. It seems like it's the Wii remake, but I've seen some stuff online that maybe it's an enhanced version of it. Once some more information surfaces, I'll definitely be adding it to the site...and my collection

@everyone - Those have all been added!

just getting back on to log games after a bit. regarding Ori: the collection for switch. I bought it new and just opened the case. It has a download voucher for the soundtracks but both Blind Forest definitive edition and Will of the Wisps appear to be on cart.
