Off the top of my head... 1. Pso ep1&2 2. Destiny 3. Fallout series 4. Battlefield series 5. Runescape (yes, but jagex f'ed it up) 6. Guitar hero series 7. Goldeneye 8. Pokemon ruby/saph/emerald 9. Gta series (mostly 3) 10. Shadowrun (with friends) The reason destiny gets #2 is because it has the right balance of challenge and competition. Although it has it's flaws at the moment, I will not stop playing it. Bungie cannot possibly screw this game up more than it is, and I'm still having a blast (don't take that as a challenge :P) Hopefully 14 years from now (pso released 14 years ago) ppl will still try to play destiny online despite no official servers. I bought a wii just to mod it, just to play Phantasy star with maybe 100 other ppl online. Who's to say that in the future I won't buy an xbox 720 to try and play destiny when bungie abandons it. Joking of course; I'm sure they will release some kind of pay to play system when it dies. Think about that for a second... Pso is #1 because after 14 years since its release, after 1000 hours of in game play time, I still find myself coming back to play it again. Destiny captivates me just as much as pso did when I first discovered it. To 1000 hours of play time, and then some :) Note: I am casual gamer, and seriously don't take that as a challenge lol
