To make it clear:
All other MMORPGs except RO:
1. Walk to spawn spot of monster that you want / need to kill.
2. Kill it.
3. Wait until it respawns.
4. Jump to 2. (repeat forever until quest done or you are bored)
Many of them feature targetting by pressing "tab" and auto attack by pressing "1" (if you hotkey auto-attack there). So all that game is about is pressing tab,1,tab,1,tab,1,tab,1,tab,1. Nothing more to it.
You won't actually see much of the world. Especially not with party members, because why would they go into a region without the spawn they need? Most regions off the main path usually don't even have any monsters on them. There are never any surprises, no monster will suddenly spawn next to you (unless you stand at a spawn point but then it was there in the first place). Usually even the respawn time is as low as 5 seconds, there is no way to "clean" an area, no room for "mobbing" techniques. If you let monsters follow you, they will usually turn around and walk back to their spawn spot.
This kind of gameplay is soooo boring and the reason why I generally strongly dislike the MMORPG genre.
Ragnarok Online is different. Here if you kill a monster, it will spawn somewhere else. You will need to explore the whole map to find it again. You can actually clean up an area of the map. If you find a region of the map where nobody ever goes to you will be surprised by a massive amount of monsters being there. You can play with a party and actually WALK around. You can define yourself some kind of "Hey let's try to play through this dungeons without using flywings" goal and have fun with a party.
Only in RO this all is possible and it's thanks to one thing - random spawn locations.
I've never found another MMORPG that has this.
