I think you will probably understand Nostalgia more in 20 or 30 yrs time. Those of us still alive and playing will probably be stepping into 'Hololdecks' and saying to each other, "i remember the good old days when the (current gen console name) was the top dog...What a machine that was"
Some of us older members of the commune are well into stuff like Dragon Spirit, R-Type, Ninja Spirit, Dig-Dug,Galaga etc,etc and these are just the kind of things the PC Engine does well. I prefer to play this type of game way more than the likes of COD or Halo. Does'nt mean that i dont like playing COD or Halo though, its just a matter of my own preference. Sheep's more or less of the same age group as me and im pretty sure he would get a real kick out of playing games on a PC Engine. That would probably be largely down to Nostalgia but that's no bad thing anyway. 
As a matter of interest, what are the 2 or 3 games you consider might be worth playing?
I've decided that either PC (+ emulators) or Wii (for now, + homebrew) is the best console ever. Wii because I really like the GameCube's library of games. In time, everything is on PC, and when it is, you can decide exactly how you want to play it. Example: I definitely didn't want to play Zelda with a NES controller. It's boxy edges leave much to be desired. Playing it with my Xbox to PC adapter was much nicer. (Note: I hate the Xbox/360 controller, but it's the only controller I have that plugs into my PC)
It seems to me that MAME or Namco Museum Virtual Arcade (360) would be even better at playing Dig Dug. I don't like normal shmups that much, but to my knowledge the first or one of the first games I ever played was Pac-Man.
I like good games. Doesn't matter when they're from. I don't even like CoD or Halo that much. If TimeSplitters: FP worked on 360 with online, I'd be playing that. But some games were never good to begin with, but it didn't matter because they were among the best of their time. So I ask myself: In 2009, which is better: Bomberman '93 or Saturn Bomberman? I just beat the original Legend of Zelda game yesterday for the first time. I needed save states, because the Nintendo of the 1980's was stuck on two ideas:
- Designing arcade games that generate money
- Giving people really hard games so they think they have their money's worth
Really I didn't use them too much, just for an unlimited supply of money and whenever I started a room full of blue wizzrobes.
I think the looking at the title of "best game ever" through rose-colored glasses is sad. The Legend of Zelda: Ocarina of Time looks terrible. Only through the use of emulators and high resolution graphics packs does it become playable. I'd much rather play The Legend of Zelda: A Link to the Past or The Legend of Zelda: The Wind Waker. Both games look better and play better.
