Hi there, and welcome to Runes of Magic!
The size of our tends to fluctuate, which happens with all games. And, depending on how you want to play--PvE or PvP--some servers will have larger, or much larger populations than others do.
For PvP (Grimdal and Indigo), the populations tend to be rather smaller than on our PvE servers. Of the two, Grimdal is the older and has the larger population.
For PvE (Artemis, Govinda, Reni, Osha, and Palenque), the populations are all larger than on the PvP servers. Artemis is the oldest server and probably has the largest population. Govinda has the next largest population, with Reni and Osha swapping third place back and forth between them. Palenque, our bi-lingual (English/Spanish), is the "youngest" PvE server and has the smallest PvE population.
A note about Palenque: While many or most of the players there speak English as their primary language, we do have a fairly large number of Spanish-primaries there. Quests are displayed in English, but system announcements and the Item Shop are displayed in Spanish. And, during events, the staff members speak and respond in Spanish, though they can and do speak and respond in English, as well.
I won't make any recommenations as to which server you should choose. I'm sure that one or more of our usual forum denizens will be willing to do that.
