This is exactly how I feel. Back when FFXI launched back 10 years ago? I was so caught up with exploring the then massive world that it took me nearly a year to hit the first cap. The world being so big had you travel to all these obscure places to level and that really hit it in line with the adventure and journey to end game.
Yes, it was satisfying.
But I'm not sure I can do it again, hell, I'm not certain that SE could do it again without having people cry terrorism at them. It's an old system and it's definitely not user friendly - but I was glad to be apart of it.
Time has changed and we're set to play something within comfort until we hit cap and try difficult things again, I'm fine with that. A lot of the OF people are too caught up nostalgia that they don't realise exactly what it is they're asking for.
All I am referring to was mob grind.
Sense of adventure? I am all for it. A bit slower progress? I am not against it. I REMEMBER how it was back then. Getting Genkai quest item was a MAJOR task and it was fun. Getting your AF felt epic. I thought it was a big deal when I got Sandoria Rank 10. The first time that I killed Zirat Boss's boss in Tulia. The first time getting all 4 triggers to spawn Kirin. Camping Kraken with friends for hours... Wiping on Fenrir when it first came out... Then Diablo when that came out... One of the COP quest where you first saw bahamut... and etc etc.
That's the fun I had, not the mob grind though.
