Very true. I’ve had the pleasure of playing NES Contra on a Play Choice 10 cabinet. The cabinet and arcade-stick experience makes this contrast even stronger: it’s simply more fun than the arcade version, even if the only thing that’s different is the software. And if you want to get technical, it’s also running on inferior hardware to boot.

Hands down: Bionic Commando (NES).

The arcade game is an exercise in quarter-eating frustration, with difficulty on par with Ghosts and Goblins only with harder movement tech. I promise you, the next time you boot this in MAME, you’ll move on in under three minutes, possibly never to return.

The NES version is a platforming masterpiece of difficulty scaling, minor backtracking, lightweight inventory management, all with a nice side of world exploration to tie it all together. It even has Commando-style mini-games to break up any possibility of monotony. It’s a solid playthrough that has all those elements, but nothing is overdone or gets in the way of the action.

Sweet jebus. You’re jumping into one of the biggest (if not the biggest) game console libraries ever. There’s a lot to pick from, and… there’s a lot of trash too.

It may not be to everyone’s taste, but I really enjoy the Burnout series. Each title brings something new to the table, and the music and energy just don’t let up. The only problem here is the brutal load times between every level, which on emulation, probably aren’t going to be an issue for you. The licensed soundtrack is also something of a time-capsule now, so it may be worthwhile on that point alone.

There are a few Castlevania titles for the PS2 as well. These are a fun departure from the side-scrolling formula, and seem to have learned a few tricks from Devil May Cry. They deliver on mood and challenge, but I wouldn’t rank them as high as the GBA or PS1 titles. Still, they’re fun to play.

If you wind up short on recommendations, I’ll add that PS1 titles should get an honorable mention here. The PS2 is fully backwards compatible with the PS1, so those cream-of-the-crop titles kinda/sorta count. For a lot of us, that was a big part of the experience of owning one of these machines as your library just kept growing into the new console gen. But you’ve probably already heard of Metal Gear Solid, Symphony of the Night, FFVII, WipeoutXL, Tony Hawk, and so on.

The 2600 depicted in the article thumbnail, was absolutely a beauty in its native environment of the late 1970’s:

Especially these days. Current-gen x86 architecture has all kinds of insane optimizations and special instruction sets that the Pentium I never had (e.g. SSE). You really do need a higher-level compiler at your back to make the most of it these days. And even then, there are cases where you have to resort to inline ASM or processor-specific intrinsics to optimize to the level that Roller Coaster Tycoon is/was. (original system specs)
