Um, questions. Since its been a long time since I've actually done an RP and I'm not sure if I even have the time to even slip RPing in my timeline, is it alright if I make a character sheet or a universe sheet and apply but only use it when I am available? Also, is an alliance between the Zerg (Starcraft) and Tyranids (40k) too op? Is there a limit for opness?

Really, all these questions are due to the fact that I haven't been RPing for such a long time and want to get back into the groove of things.
