DEAR FUCKING GOD. Now Flyff is a horrible HORRIBLE grinding game. HORRIBLE. I'd rate it almost as bad as SRO in terms of grinding. Flyff was basically nothing but skill spamming. And you HAD to have a RM or assist with you for buffs and healing. So nothing more than click click click, kill a couple thousand things for one green drop.
Anyways, Mabinogi has its part time job system where if you have no skills in a particular field, they give you easy delivery or collecting but low paying jobs but increase your rank of a skill and they upgrade the job to say... tailoring clothes or whatever is the specialty of the shop but they pay you more exp/money/items. And the combat isn't skill spamming or anything. If you do nothing but attack, even a weak monster is going to kill you, much less the things your level. You have to watch carefully and predict in advance the monster attacks and skills. And you need to plan out your leveling too because how old you are when you level affects your stat gains. Starting off young gets you more AP as you age and more hp/str/luck but starting off older can get you more mp/int but less hp and less AP as you age (Of course, we all want more AP and to be dumb as stumps, FUCK int, so we all start out as 10 year old lolis). So Mabinogi actually requires more thinking than you think. Of course, the people who can't plan ahead or do something else besides spam skills and click on constant attack would probably call it shit since they don't have the intellect to play it but hey, to each his own.
