Finally got mine.
Man does Vajra suck! Move the cursor around to shoot at the giant flying robot sprite. Of course, it's impossible since he's shooting at you and you have to shoot the incoming bullets while also trying to hit the robot. Each level is a 1 on 1 duel with a big flying robot sprite, laid over some rudimentary CG city fly through laserdisc footage.
Some guy is selling Vajra 2 on ebay for $850!!!!!!! No thanks. Next Japan trip I'll scour the used LD stores for it, I guess.
Anyway--I find it hilarious that this system was so expensive at launch, but yet has no S-Video out. The composite that comes out of this thing looks awful! Considering the fact that this LD has AC-3 optical out (a rarity for the time), it's strange that it doesn't have S-Video.
Anyway, LaserActive games show up on ebay from time to time, but usually for outrageous prices. It will probably take me awhile to build up a reasonable collection--but there are very few games anyway so it works out.
