I tried playing Marauder a bit after reading your review, and what you wrote seems spot-on. Interesting twist on the Berzerk formula, but it got old fast.
BTW, from the review:
You know I've nearly exhausted the Atari 2600 catalog when I'm reviewing games like Alpha Beam with Ernie.
When you wrote that I thought to myself "No way, there must be tons of great games left to cover." But then I checked it out and, wow, you've gotten remarkably deep into the US library! As far as I can tell, this is roughly what's left:
Air Raid
Basic Math - Math
Beat 'Em & Eat 'Em
Berenstain Bears
Big Bird's Egg Catch
BMX Air Master
Cakewalk
Challenge
Cookie Monster Munch
Eli's Ladder
Extra Terrestrials
Gamma-Attack
Gauntlet
Glib - Video Word Game
Guardian
Harem
Hunt & Score - Memory Match
Ikari Warriors
Kung-Fu Master
MagiCard
Master Builder
Math Gran Prix
Motocross Racer
Music Machine, The
Obelix
Oscar's Trash Race
Out of Control
Red Sea Crossing
Shuttle Orbiter
Smurfs Save the Day
Sneak 'n Peek
Stone Age
Universal Chaos
Video Jogger
Video Life
Video Reflex
Wall Ball
X-Man
Many of those are super-rare (though you have a Harmony cart IIRC), have graphic sexual imagery, or are edutainment titles. But there are also some interesting games still left in there, like Shuttle Orbiter and Kung-Fu Master, or Universal Chaos, a port of the old arcade game Targ.
Of course there are also homebrews, prototypes, and PAL games that have been converted by fans to NTSC (which is pretty much all of them), so the Atari will keep giving indefinitely.
You haven't lived until you've played the PAL exclusive game Walker, aka Clown Down Town. It's like the East German Stasi tried to program a video game -- it's "Worker and Parasite" from The Simpsons come to life.
