I'm looking for LITRPG stories that keep the game system fresh things like dungeons, stats, titles, anything that add a sense of depth into the game. 

I especially love when LITRPG stories give the feeling that the players are in a much much smaller part of the world, that many more things are to be discovered. 

I love adventure in a story and unique combat but not ridiculous and unrealistic. I crave that connection between characters that so few authors can craft. The friendships in a story are highly enjoyable for me but sometimes conversation can seem forced and unrealistic.

I'm asking for LITRPGs stories that do one of these really well without being a complete turn off.

I'm usually not a fan of authors promoting their own work, but I think mine fits your criteria. Although my side character development needs a little extra work.
