I liked the Metroid Prime and Splinter Cell.
Also, when Super Smash Bros 64 came out, I thought it was humerous. That's what kept me watching that commercial. Strolling down flower-filled fields, holding hands in harmony. Then, someone get tripped and all hell breaks loose. That was funny and I loved watching that commercial every time I saw it. Great-looking games like MP and SC kept me watching the commercials because they both looked good and they were both great games with great gameplay(MP has better gameplay, IMO).
