The gameplay in FFO is very accurate despite fewer on-screen enemies than the incredibly hectic and awesome arcade version and the extras are pretty cool.

The new characters, new battle system, the Krypt and psuedo-3D engine all help make the portable version of Deadly Alliance a decent experience.

It is far from perfect, with the lack of battery saving, the lack of in game music and not being able to keep the weapons collected in a level. However, good graphics and well executed play mechanics keep it above mediocrity.

Stat hounds beware... the lack of depth, all the MLB ballparks, current rosters and trading will really turn you off... [but] easily the best GBA baseball title on the market for the time being.

Each game can be played for a few minutes at a time or a few hours at a time if you're addicted.

If you've got the retro bug, you could do much worse than this collection of Namco classics.

An awesome multi-player title and a perfect travel companion that can be played in quick ten-minute bursts.

Decent. Well thought out. Done before.

Doing the classic Konami trick (up, up, down, down, left, right, left, right, B, A) on the title screen of each game will yield a surprise.

Exploring the mansion and capturing ghosts is an engrossing experience, despite being a tad light in the depth department.

Some average gameplay and graphics team with some decent sound this game isn’t horrible but not great either.

It's a little banged and bruised, but it gets where it's going.

Nothing innovative, nothing truly new, just the same comfortable game we've known for years.

It's all pretty standard platforming fare with nothing to really distinguish it from the rest of similar titles except for the license.

The extras included in Mega Collection could have been spiffier, but they're interesting enough and round out the package well.

Just isn't a very enthralling game.

Just isn't a very enthralling game.

The graphics are average at best, the control has issues, the load times are nearly unbearable and the constant one-hit deaths will really get on your nerves.

Essentially a good game hampered by some careless oversights. Some levels will force players to endure countless deaths (falling into bottomless pits), the camera system is archaic and some bosses are cheap as hell.

It suffers from hideous framerate problems at times but the texture detail is high.

The most adult themed game yet to reach consoles. It features loads of mutilation, blood and gore, accompanied with lots of bad language, none of which is bleeped. In short, this isn't one for the kiddies.

Sonic and Shadow's levels are great, but every one else's levels are, unfortunately, dull. In the end, 1/3rd of the main game is great but hampered by camera and some control issues.

The gameplay itself is shallow and boring.

Worse yet, there is STILL no save option, it uses passwords, which there is no excuse for anymore. You can find cheats, but with the lack of a save feature you better write them down in a safe place.

It is sloppy, mundane and unforgivably short.

Just too difficult to be fun.

The graphics are good, the music is pretty good and the varied gameplay sets it apart from other games in the genre.

The graphics are fairly impressive by GBA standards, especially if you look at some of the finer details. Unfortunately the visuals are effected greatly by the onscreen display which really limits how much detail you can actually see.
