I will pity you:
Hucards:
Chase HQ (I like it, but...)
Dead Moon (OK shootemup, nothing special, but nice)
Shockman/Shubibinman 2 (HOLD OFF--this is an acquired taste...I have yet to drink the kool aid. Shubibinman 3 CD, however, really is fun, but WAY TOO EASY. BUT WAY, WAY, WAY fun.)
CDs:
Super Darius (if you are a fan of the series, sure)
Gradius II (if you are a fan of the series, sure)
Browning (NO, for most folks. Although, it is worth it if you get it CHEAP, assuming you are obsessed with listening to all Red Book and have fun playing mediocre games...like me!)
Strider (ONLY FOR CURIOUS, big fans of Strider...I don't regret purchase, it was fun to see two extra stages, but overall, most folks won't be impressed by overall package).
Gate of Thunder (HELL YES HELL YES HELL YES)
Winds of Thunder (HELL YES HELL YES HELL YES)
Spriggan (most folks prefer the FIRST, but I also dig the sequel. THE FIRST IS FUN AS HELL, the second has already been translated and patched by BONKNUTS).
Valis (any of em?) -- This is a touchy subject. NOT EVERYONE LIKES THIS SERIES. I have always recommended Valis III, but recently I have wondered if it might get too challenging halfway through the game. IT IS AN AWESOME GAME, IMHO. I love switching between three characters and the platforming is more interesting than Valis II, which is rather simplistic, linear stage design. I AM ONE OF THE FEW ADVOCATES OF VALIS II (so, unless you love the soundtrack and average platforming...play III first). I haven't played PCE Valis I and PCE Valis IV in years and can't fairly judge them. They are both solid games, IMHO, but I need to replay them...sadly, Valis IV was not as "epic" to me as VALIS III. Playing and beating Valis III feels like an adventure/ accomplishment the first time!
HOW'S THAT VENOM?!
