features: like wow a chance to go out and do quests for ure tribe or w/e something like that. also like with WOW keep the quests self sufficent, like u complete a quest and then go on to do another, and u don't have to grinde inbetween. mabey unlike wow try to have the quest givers be a little more animated, or something, like try to helpo make it seem that they really need to get w/e done but this is just a sugestion
powers: i think like the way oblivion did it is good, like each furry get's the attribute boosts their animals do, so like keen ears, eyes, olifactory senses, see in the dark. ect shadowrun 4th edition and runner's companion have very good sugestions for furry stuff under SURGE
other racvial comunity: idk if i'd like being a furry with other races, i mean it'd sortas be like me walking around in a fursuit, i'd get made fun of ect, but on the other side it'd be cool to chill with other races, i'd sugest one massive server or country where every one can chill, and then have a specific sorta minicounty where every one of that race can be togeather. but this is just a sugestion
species: wolf, fox, tiger, dog, they are very common, and if u can try to get muzles in there somewhere (yes furrys like to have muzzles (even one like the kaijjit from oblivion) i think) and those are very common and basic sugestions, a servay would help get other ideas, but here, we have a few wolfs and foxes, and we had a tiger and we have a dog ect
i hope this helps
