We've discussed the 2nd RPG you've ever owned and the RPG you own but have never played (and truly wish you did) and now we have the next question: Which RPG do you wish you owned but never have?
For me, that's Space Opera (it would have been tied with Empire of the Petal Throne, but I snagged a copy on eBay recently).
See, back in my early days of gaming, complicated systems never upset me (I avoid them like the plague these days tho'). I always wanted to get and play Space Opera. Heck, I'm not even sure why - it just seemed to be that really great game (based upon reviews from people in my extended gaming circle in my High School and College days) that I haven't even physically held, let alone played a session of. Just heard the stories, and they were awesome.
I see it's available in RPGNow in PDF, but apparently the scans are really poor.
Damn, now that I've thought on it, I may have to troll eBay for a copy at some point.
