I copied this from AtariAge as I generally share this opion:
My favorites out of the original GCE games:
3D Minestorm
3D Narrow Escape
Armor Attack
Bedlam
Berzerk
Clean Sweep
Cosmic Chasm
Fortress of Narzod
Hyerchase
Mine Storm
Mine Storm II
Pole Position
Rip Off
Scramble
Star Hawk
Web Wars
There are a lot of great homebrews as well. I recommend getting a VecMulti to load both original and homebrew games onto the same flash cart.
Birds of Prey (Phoenix)
Bloxorz (beta)
City Bomber
Moon Lander (Lunar Lander)
Nagoya Attack (beta)
Omega Chase (Omega Race)
Patriots (Missile Command)
Protector (Defender)
Rockaroids (Asteroids)
Rockaroids Remix (Asteroids Deluxe)
Space Frenzy (Space Fury)
Spike's Water Balloons (Kaboom)
Star Fire Spirits (Star Wars Arcade)
Trakkers (Targ)
Verzerk
Wormhole (Gyruss)
YASI (Space Invaders)
I should add Vector Patrol whch is an amazing and fun Moon Patrol clone.
I play mostly with my multicart(s) and don't use a lot of overlays. The Minestorm overly is almost always inserted into my Veccy.
Do a lot of YouTube and form an opion! And buy a multicard for starters
