Hey. I think nobody really knows besides SNK and maybe CM. Would be cool to get at least some snippet of information regarding that. The last blade 1 and 2 are my absolute favourites fighters from neogeo era (not that I'm good at them or anything). It's true that they always lived in the shadow of SamSho series, which is a darn shame if you ask me as I love the design, thought that went into it and overall vibe way more in TLB games.

I've asked this same question as you a good couple of times on various forums, sent an email but never got any solid answer as to what the masterplan is regarding this series or exclusion of some games. I do have TLB1 here, TLB2 on steam but would love to have it on gog too. It's the most deserving place for games like these, although the online aspect won't muster the same numbers as on the larger platform, as unfortunate as it may be.

There are 3 PC vendors I know of that offer neogeo snk games: gog, humblebundle, steam. Gog and HB offer the largest collections, steam has considerably limited availability:

Steam has TLB2 and KoF'97 iirc that are exclusives there, but they lack like a half of other games.

HB has Neo turf masters exclusive afaik. However their ports mostly (if not all of them) run on some basic emulator and do not feature CM's ports etc. Maybe it's stripped down dotemu or hb's own launcher, I don't know.

GoG imo has the best supported collection, missing only TLB2, KoF97 and Neo turf masters. Would be rad to have them here as well. Hopefully one day we can play as Hibiki here too and be merry! ;)
