Gotta say I am loving the titles that are already available/announced but there is always some hidden and burried gems in the past that are long overdue to be on our current systems.

My list:

Cadillac & Dinosaurs (Arcade)

Looney Tunes Sheep Raider (PS1)

Tom & Jerry in House Trap (PS1)

Pink Panther Pinkadelic Pursuit (PS1)

Ooga Booga (DC)

Having those games on my Switch2 would be a dream come true 

I'd love the old NFS games but that's probably a no-go from a licensing standpoint (especially for PS2 era onwards) which sucks.

Bugs Bunny Lost in Time, Donald Duck Quack Attack, Colin McRae Rally 1/2.

If they do any PS2/GC titles then Scooby Doo Night of 100 Frights.

Too many for me to list off the top of my head so I'll just go with some of the licensed stuff that, unfortunately, probably won't make it:

Castle of Illusion: Starring Mickey Mouse - Genesis
Ghostbusters - Genesis
Batman - Genesis
Batman - NES
Willow - Arcade

I hope somehow the Simpsons beat em up arcade game can come to this.

Faxanadu (NES)

Ultima (NES)

Quintet trilogy (SNES)

Popful Mail (SCD)

Vay (SCD). Yeah, I have this on Steam, but I would like to have it in my Switch 2 RPG collection.

The N64 Goemon games (a lot of Konami games are on Arcade Archives)

Virtua Fighter 2 and 3 (Arcade/Saturn)

Guardian Heroes (Saturn)

Princess Crown (Saturn)

Sakura Wars (Saturn) - this is an extremely long shot, as these games never got official English translations, and I doubt that Hamster is going to sink money into a venture like that, but this is a wish list, after all)

Thousand Arms (PS1)

Dead or Alive 1 and 2 (Arcade)

Tekken 3 (arcade)

Pengo (arcade)

Aside from licensing issues (I'd personally have loved to see The Simpsons and Nintendo's Popeye game come to Arcade Archives), keep in mind that Hamster pretty only does games owned by Japanese studios, as they have never had any American arcade games in AA except for Qix, which was developed in the USA but is owned by Taito and Square Enix. I have posted on their FB page suggesting to them to make a deal with Warner Bros for Midway's arcade catalogue, since WB isn't doing anything with it. I do hope that Hamster is looking at Western-produced games, but I wouldn't hold my breath right now.

My Wishlist:

-Virtual On: Cyber Troopers (Arcade)

-Smash TV (Arcade)

-Total Carnage (Arcade)

-Starblade (Arcade)

-X-Men (Arcade)

This is something that I hate about some companies, they prefer to leave their best projects root to the oblivion than being more open about letting them to be easily acessible on other channels. Not saying to give them away, but to put a small fee that doesnt repel the ones that are making an effort to bring those games back to the notoriety

Anyway, of the games they've announced so far, the one that interests me the most is Dezaemon. Rhapsody would be a good choice, but I have that as part of the Prinny Presents Volume 3 collection, but it's nice for people that would like to pay less to buy it a la carte.

All that is available via emulation. Basically, anything pre-ps3 is easy to figure out, including arcade games.

Emulation unlocks so much.  Take Shining Force III, both scenario 2 and 3, never launched outside Japan, but fans roms exist in English. 

True dat, but there is always some minor inconviniences with these extra oficial emulators, like lacking of local mutiplayer and some visual/sound bugs. 

Also for me, To use the least of systems for my gaming time is a plus. So being available on current systems is a nonbrainer
