BLAST CHAMBER:
This is one of the first games that was made for multi-tapping mayhem!
It's pretty old,... but still very enjoyable to play.  It's a simple idea
really.  You're a person stuck in a box.  You have to get through obstacles
without killing yourself.  In the multi-player aspects of the game, the
idea is very much like soccer... except you're allowed to push and shove
your opponents (into a pit full of spikes).  You need to get possession
of a star-like object and throw it into one of your opponent's basket.
Everytime you make it in, you take away their time to live.  The idea
is to get rid of your 


BOMBERMAN WORLD:
Just go out and buy this game right now!! Don't waste time reading this!! 
Well, if you really want to know what you're buying, here's a small
description.  You're in a maze full of walls and you're this dude with
bombs.  There are several other dudes with bombs out to kill you...

PROS:
VERY FUN GAME!!  Like I said,... don't waste time reading this!  Don't
worry, you can go out and buy it and then come back and read the rest.

CONS:
Umm...  not enough players.  Still waiting for a version that supports
up to 8 players.


WORMS:
Worms is the most funniest and most intellectual game I've ever played.
Everything is based on sheer skill of physics and mathmatical reasoning.
However, the thought of killing innocent worms for pleasure is just awesome!
Plus you get a large choice of weapons to choose from to pulverize your
buddies!  This game is technically consisting of 16 players.  You can 
have up to 16 worms on the screen, but I would recommend 4 players for
this game, as it will take a long time for it to be your turn.  


PROS:
This game is seriously addictive once you get the hang of it.  It's just 
a matter of practice, practice, practice.  You'll get it as you find yourself
glued to the controller.

CONS:
The graphics are a little bit tiny so it's a bit hard to realize that those
little pixels are your worm buddies.  Worms 2 has remedied that problem
and added additional weapons!!  Now hopefully they'll release this version soon
for the Playstation.
