Taito Legends 2 is ace. <3 I was so delighted in the pants to see that it had Cameltry on it. It's probably still my most played game on the collection! The original Taito Legends wins for New Zealand Story, Rastan and Ninja Kids (ENGRISH GO), but a few of the really good games are very badly emulated. I dunno if they fixed that up for the American release, but the likes of Bubble Bobble, Operation Wolf and Rainbow Islands are terrible. Constant slowdown, muffled, off-sounding audio and sprite flickering. ;__;
I'm a big fan of these retro collections, Activision Anthology on PS2 is still my absolute favorite. There's like over fifty 2600 games, with an amazing menu screen set up to look like a room from the 80's, complete with a stereo that blasts out some fantastic tunes from that era (SAFETY DANCE). You choose your games by picking up the actual cartridges (well, you know, not... the actual.. ssh), which can be rotated around for no reason. They've also chucked in TV ads/spots for the games, as well as a great video from '82 where Activision are giving themselves pats on the back and announcing a new multi-million production plant, little did they know the video game crash was coming!
Some lost the plot with these collections though, hello Atari Anthology, why is your menu screen so difficult to navigate? Why do I have to wait up to thirty seconds for ATARI 2600 games to load? And Intellivision Lives! has NO SOUL. It's also very difficult to play, but that's mainly because of the systems obscure controller, there's no way for a PS2 controller to emulate that terror correctly.
And where's Streets of Rage in this Genesis Collection? Half those games have already been avaliable in Sonic Mega/Gems Collection.

But it's nice to see they haven't totally forgotten about Alex Kidd, even if Enchanted Castle is the worst in the series.
Jam it back in, in the dark.
