Someone who has been playing games (in my case exclusively PC games since Windows 95) for years. Therefore being very knowledgeable about all the genres of games (fps/rts/mmorpg etc). To the point now that no game satisfies me since I've seen everything. Its the same repeated formula with better graphics. Kinda like Iphone and Samsung Mobiles LOL. Humans have saturated their creativity it seems.
Watch when Cyberpunk 2077 finally does comes out, it wont be any different than GTA 5. Not saying that's a bad thing since a casual gamer would definitely enjoy gaming more then a veteran. For me the game is about the journey and not the endgame. Thats the only way to enjoy it but i tend to favor multiplayer games rather than single player for obvious reasons.
Hardcore Gamer plays games all the time, with multiplayer games being a second job (mmorpg).
