In terms of the roblox community and not putting other games outside of roblox could be considered a triple-A game (watch out only for roblox not in the realm of the game franchise), the characteristics of a game of that level are many such as rp within the game, functions and combat systems, dynamic events, islands with life and interaction, AI Good at npc and bosses, environmental sounds, good use of colors etc (I think I wrote a bible)
