I've molded my whole fucking life after Starship Troopers by Robert A. Heinlein (love his other works too) just wanted to say that if this guy had started a cult i would have probably be in it, my other favourites fall in with my favourite authors: almost everything written by Jules Verne with my favourites being s Mysterious Island and Journey to the Center of the Earth i've re read them so many times that i memorized parts of them, other authors that i like are Robert E. Howard for the Conan series and the Steve Harrison stories, Solomon Kane is good but not that good imo, of course the genius work of Dan Simmons with the Cantos of Hyperion, those 4 books were the first to make it to my little collection along with my 1982 edition of Starship Troopers
other notable favourites of mine are Joe Handelman's Forever War and its sequels
Today's sci fi im afraid to say its pretty shit and its not easy to find something good, im still looking for the best work in the genre, but for example the Hugo and Nebula awards have lost alot of credit and are now basically meaningless
