From what I've played so far, it's a kind of Earthbound-esque RPG with a similar humor to the comics.

The art is beautiful, but I haven't gotten to the real combat yet.

Because if you're around frogs you might get lept on? Genius.

I don't know if you played it, but there was a totally different Game Boy Sunsoft Batman game. Also very good, and it has one of the kickinest soundtracks of any GB game I owned!

Batman the Video Game is a sick cut. Sunsoft was doing some good shit.

Great console. Never going to recommend it to an emulation beginner. Honestly, it was a stretch to even recommend N64 games. Emulation for those are all wack as well.

A _lot_ of PS2 games have busted PC ports or ports with invasive EULAs. PS2 is still probably the best way to play GTA: San Andreas.

But really, just pick a console with a graphical aesthetic you like and find the games people buzz about. I'll give you some recommendations, based mainly on my taste, but a quick "(console) best games" search can help you expand upon this.

NES:

Mike Tyson's Punch-Out, Super Mario Bros 3, Kirby's Adventure, Castlevania, Mega Man 2, Contra

Genesis/Mega Drive:

Streets of Rage 2, Castlevania: Bloodlines, Road Rash, Sonic 2, Contra Hard Corps

SNES:

NBA Jam: Championship Edition, Mega Man X, Star Fox 2

PS1:

Crash Bandicoot 3: Warped, Crash Team Racing, Tony Hawk's Pro Skater, Metal Gear Solid

N64:

Super Mario 64, Star Fox 64, Banjo-Kazooie, Mario Kart 64, The Legend of Zelda: Ocarina of Time

Dreamcast:

Sonic Adventure, Sonic Adventure 2, SoulCalibur

PS2:

GTA San Andreas, Tony Hawk's Pro Skater 3, Tony Hawk's Underground 2, Resident Evil 4, Silent Hill 2, Metal Gear Solid 2 & 3, Kingdom Hearts, Kingdom Hearts II, Sly Cooper (entire series)

GameCube:

Super Mario Sunshine, Mario Kart Double Dash, The Legend of Zelda: The Wind Waker, Super Smash Bros Melee, SoulCalibur II

Xbox:

Halo, Halo 2, Fable: The Lost Chapters

That's a decent start, but not comprehensive by _any_ means. Just pick a console with games you like the look of and search the top-rated games, the cream really rises to the top when you're looking for retro games.
