I remember back in classic FFXI when i'd be riding along on my chocobo to some quest of some sort and an odd named monster would catch my eye. I'd do a check on it and then i'd get that great thrilling feeling when I saw it come up as "Impossible to gauge.". I didn't care what it dropped or if it'd 1 shot me. I HAD to get off my chocobo in the middle of nowhere and fight it. The thought that it could actually drop something besides 6 Gil or an earth crystal was great and that it could have attacks I have never seen before was so thrilling. I really miss those moments of random NM encounters. Even those ones that one shot me. XD
