Mega Man Legends 2
When Mega Man first appeared on the PlayStation in 3D, purists cried foul. "Mega Man doesn't have a helmet!" Whatever. Mega Man Legends was a nifty way to break the Blue Bomber into the 3D world with grace, albeit a blocky kinda grace. The sequel, which follows the side-story featuring Tron Bonne, brings a host of improvements the original lacked, including perhaps its most useful feature: lock-on targeting. While this addresses one of the more annoying quibbles from the first Legends, it makes the game much more enjoyable than you might think. While navigating towns and houses, talking to people is considerably easier since you don't have to line yourself up just right in order to get a response out of someone. Now you just hit the R2-button and voila! Instant lock-on. Although it's handy while talking to townsfolk, it's downright necessary when circling a boss, or multiple enemies, where strafing is required. Another aspect of the game that has been improved is the sheer size. ML2 brings twice the enemies, and a world-map twice the size of the previous game. While the game's engine is certainly able, the camera is still high-maintenance, requiring you to manually adjust it at almost every turn. This helps avoid autocamera troubles (they just never seem to work right), but it's still a bit of a chore. However, I liked the original Legends, and these improvements are enough to bring me back.
As one of the biggest skeptics when Mega Man went 3D, I found enough gripes about the first Legends to keep me from getting as absorbed in it as I did with the old NES games. The sequel, though, is actually a fun little game with a lot of improvements in gameplay and appearance. By adding analog support, tweaking the homing system, enabling movement while firing, and fixing some of the camera issues (notice I didn't say all), Capcom has really refined this branch of the popular series. Storywise, it pretty much flows from the first Legends with the same characters and plot, so if you liked the original, you'll surely enjoy this game.
Sure, it might sound a bit blasphemous, but I believe the Legends series is the best thing to happen to Mega Man in years. Really. The first game, even with its bland dungeon graphics and awkward control, was an incredibly enjoyable action/adventure, and its sequel delivers an even better experience. Nearly everything has been visually upgraded a stunning amount, giving Legends 2 a truly cartoon-like appearance. There's much more focus on the story line, complete with loads of in-game cinemas, and the control has been tweaked. Legends 2, aside from being a bit too lighthearted at times, is easily one of the best 3D adventure games on the PS.
