Revelations: The Demon Slayer/Megami Tensei Gaiden: Last Bible [Game Boy Color/Game Gear]
Description: As the second Megaten title to hit outside of Japan, it really shows Jack Bros what for. Going a more traditional, Dragon Quest-y route instead of the 3D dungeons, Revelations retains its Megaten roots quite well. You have the option to talk a monster into joining your party, along with summoning them to fight at your side in battle. Although, you can only have one of the same kind, encouraging you to get as many different and powerful monsters as you can. That's not to say some of the ones you have are flat out useless, as you eventually get access to the ability to fuse them into even greater monsters. You also gain two other non-monster allies (one with said fusing ability, and one who acts more as a mage). The story is a bit strange and, at times, a bit hard to follow, but you'll usually know where you need to go. There is benefit in doing some exploring though, as you can get some powerful hidden monsters by collecting certain items. As for battles, everything is pretty traditional, no real bells and whistles other than monster talking. Difficulty is fairly decent, and if you're pretty wise about getting good monsters, you'll be able to let them take care of any battle difficulties with ease. For a 1992 game, it's rather impressive, but it does show its age in some areas. The graphics aren't all that great, and the music, while catchy, has that early gameboy game feel. Control is a bit slow (without frameskip) until you get the flying ark, too. The game gear version looks and sounds nicer, and goes a tad faster, but it's all japanese, which can be a bit of a problem. This is a pretty good classic RPG if you like those sorts of things, however beginners might get bored a bit quick and potentially have some trouble with the early difficulty spike.
