I'm reading this topic in the middle of playing VC Secret of Mana after god knows how many hours now (going through to level every weapon, spell and character in the game right up with the best armour) so, yeah. I would also say Pokemon, and Dragon Age took me bloody yonks to complete (only got around to starting and finishing it recently).
Honestly, the thing that's affecting my playtime of games at the moment is a startling lack of income (disposable or not) so I have to really make games last a long time at the moment. D:
