It just goes to show you that gameplay is where it is at. After all, people still rave about new games like Castlevania, Gradius V, Raiden Fighters Aces, Muramasa, Alien Hominid and the like. Most of them are damn near identical to what you play on the TG/PCE, just with better graphics.
If a game is truly good, and not just a fad, it will *always* be fun.
The PC Engine just seems to have a lot more of those than the other systems from the era, in my book. Most of the friends I've shown the system to agree. It's aged remarkably well, particularly the imports.
I still think it's the single greates system for shooters.
