I'm not a great Civ player. I've been off-and-on addicted to it since Civ4, and always getting better, but I'm just not a Deity-level player. I hang out around King/Emperor depending on how challenging I've set up the rest of my game. I re-roll a lot. I get frustrated or bored or distracted by the next shiny thing and abandon most games. I don't particularly care about "winning" them, really. I like to build things and try different strategies and see how different different playstyles can be. In the Timmy/Johnny/Spike terms, I'm very much a Johnny. I like to build interesting things and experiment with forgotten corners of the design. I also like to roleplay creating the grandest empire I can. I don't go to war much, I never attack city-states, and I try to keep my chopping down to tiles I need cleared anyway or if I really need to guarantee a wonder. I'm aware of better strategies than how I play, in other words, but whatever. It's my game and I can play it how I like it. For "Spike"-type players, I imagine Deity could be very easy once you get a handle on how everything interlocks. The optimal strategies don't change as much from civ to civ, because the limitations of the AI mean those optimal strategies stay pretty set in stone. I'm a Spike when it comes to, say, Mario Kart games. The top difficulties of those games are more challenging than 50cc for sure, but I can still expect to win almost every race. But that's because habits like powersliding for blue sparks and always holding an item behind me if possible and a bunch of other things are hardwired and unconscious to me. Trying to explain these things to someone new to the series would be difficult for me, overwhelming for them, and still I probably just have some innate talents for whatever that translate to being good at that particular game. And that's not a particularly deep game at all. Civ isn't as deep as Crusader Kings or a lot of other stuff in that vein but it's deeper than most popular games for sure. Some people are really geared-in for how to make the most out of that depth and prove mastery, and will probably feel under-served by Civ in terms of scratching that itch. But hey, the base game is free right now (though IMO the DLC and expansions are really necessary to make it feel "complete") and if you feel like Deity is too easy for you, guess what! You have friends who feel the same way, and Civ has a Multiplayer option!
