Yars' Revenge is probably the best Atari 2600 game I've played. The gameplay itself might be a bit too simplistic for some, focusing on a singular boss surrounded by a destructible barricade, but it all shines for me with the comic and whole backstory created for this game. Had I not known the Yar feed on materials to power their cannons, I probably wouldn't have known to eat the surrounding barrier instead of shoot it.

The only thing that bums me out a bit is that this never got "reverse-ported" over to arcades. If Tron (which happened to also come out the same year) could have a similar section involving destroying a barrier to reach a boss, then I think Yars' Revenge deserves to be presented with arcade board flair. It's a shame this IP never really went further.
