I dunno if its a *good* game but I just picked up Yager for 10 bucks at Best Buy. Give it a try maybe?
This next game isn't unknown by any means,but I feel compelled to maybe list it for you anyways since its 20 bucks at EB. Full Spectum Warrior.
Cheers to the folks who listed Buffy. It really is a nice game for its genre. I picked up the game instantly when I learned it was a beat-em-up. I enjoyed it so damn much I gave the tv series a chance and ever since I've been a fan of the series. +1000 to the Collective. Their Indy game is also a great one. The fisticuff action is actually abit betters than Buffys to me as well. And yes-its really too bad we never got an Angel video game. What could have been...
Just remembered a few others.
Though its been universaly panned,pick up Malice anyways. Its a basic platformer that is simple but fun. The controls and camera are good,there is alot of platforming,and the visuals are pretty solid as well,good textures and lighting to go with some nice bum mapping. The game is around a 5-8 hour playthrough.
Battle Star Galactica. Lots of cylone dog fights. Great voice overs with the cylons in radio chatter. Visuals are strong,controls hold up well,music and sound effects have a flare for the dramatics. The missions are typical defend the fleet and attack cylons but its not that tough actually. It maybe took me no more than 2-3 tries on someof the harder missions.
Good luck finding this one new though. I hunted down a brand new one for quite some time. Since my area had nothing but used ones without manuals. You don't wanna pick those up,since you do need to read the manual for some of the flight manuevers. Though there is a manual built within the game though,so I guess you could still get by without the booklet. If youre a fan of colored manuals then its worth hunting a new one down though,theres lots of good illustrations within it.
Dark Angel,another beat-em-up. This one actually plays like Buffy. In that your character has a meter that she can build to where eventualy you'll go to a more enhanced fighting mode and hand out even more damage to enemies.
Theres also a good sense of diverse combos in the game. Good combinations with Punches,grapple moves,air throws,round house kicks,Matrix like Neo air kicks,you can realy mix it up. They also added stealth elements that do get tough later on though. If youre spotted you have to sometimes take out an area with alot of guards. The game then becomes a timed battle. You have to use your rage meter,and weapons to further enhance your fighting. Once the base has been alerted to your presence you have like for example 30 seconds to take out 4 guards,60 seconds to take out 5-6. It depends really,if you sneak around and take as many as you can you'll have less to deal with if spotted. The stealth plays like Metal Gear Solid btw. You snap necks the same way,you have a radar that shows your danger meter when guards are near and how well they are alerted to your presence.
Theres also an electric shock gun that comes in short supplies of amo,where you can take a few guards out here and there in hairy situations when there are areas with alot of guards. The visuals are nothing to write home about,by that I mean you can tell its runningon an engine that looks like its been made with renderware. Sortta like a mid range PS2 game so to speak. Though it does look abit better if youre playing the game on concomponent though,everything looks more clear,textures have abit morecolor. Musicaly- its got a good use of techno within its fighting action so it really gets you into the mood of fighting. Overall its a good game,worth 20 dollars. Its a very underated game that can easily be assumed its just another licensed trash game. When in reality its acually a fun little beat-em-up.
