a list of the TLAs that I find here

[Lance Boyle]

1. PCB - Printed Circuit Board
2. DDP - DoDonPachi
3. DOJ - (DoDonPachi) DaiOuJou
4. DFK - (DoDonPachi) DaiFukkatsu
5. RSG - Radiant Silvergun
6. RFJ - Raiden Fighters Jet
7. STG - ShooTing Game
8. TLB - True Last Boss
9. FBA - Final Burn Alpha

there's tons I can't think of right at the moment and if we include numbers then the list could go on forever

WTF is a TLA

Surprisingly this list could be more useful to new players than the official(ish) Shmups Forums compendium of little-used phrases associated sometimes with STGs

TLA = Top Level A...cronym. (TSP)

What does IIRC mean?
As I recovering ludite I've been stymied by a few internet abrieviations, but I can usually figure them out with clues in the content. IMO had me stumped for a little while.
For Americans, PCE-X - Torbo Grafix 16 ( I think..)
