Pacing Question

I've been reading LitRPG long enough to want to try my hand at writing one. I know in general the pace seems pretty fast, but in other genres, I tend to like a bit of background on the characters before we get right to the meat of it. So, since I'm pretty new to this community I'm curious do you prefer to just jump right in? Or is it better to kinda wade in? Also, if this is a stupid question, feel free to tell me off.
