Yeh, i like HL2 too <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
Love the gravity gun in the last levels <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" /> and the cute doggy <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
Altough i think that the buggy doesn't drive good :-/, but there are lots of memorable levels in HL2
