Again is this normal? In terms of player retention? Is it liable to stabilise soon at not lose too much more IYO?
Depends on the game. GAAS games goes like this:
A tiny number of games actually go up over time. For example, CS, Dead by Daylight, Rust, Warframe have been around a long time and their CCU goes UP on Steam. These are abnormal. Over time you'd think they fizzle out, but they keep going up.
But you can get very successful games which start out hot, even creep up for weeks or months setting new highs, then start to die down and stabilize at a decent number.
Then you got many games like Marathon. They peak on day one, then immediately go down. Even the weekend didnt increase Marathon peak CCU. On the Saturday/Sunday, it went down vs launch day which was the Thursday right before it. This is the worst trend to have especially if the game doesnt have a gigantic starting number. Marathon's 88k launch peak is ok but nothing special given it's Bungie and the budget spent.
For SP games, it's different because they start hot and probably all of them trend down since gamers beat the game in the first month or get sick of it and it trends down.
All games typically get spikes on weekends, when there's a bargain sale, content update, it goes from paid to F2P etc...
In terms of stabilizing, just about all games do. It just depends how low the core gamers are for that game. A crap game like Highguard immediately tanked and it looks like right to the end (game ends March 12), the core fans still playing it tanked to about 300 when it's launch peak was 97k. So for this game it's stabilized at a low of 300. But for another game it might be 3,000 or 30,000.
We dont know what Marathon's stable rate is because its still a new game and dropping 10% daily. But if it's doing -10% lately, its suddenly not going to be flat tomorrow. Trending in things in business typically smooth out and not jump 10% the next day. So unless there's something that boosts the CCU like the content update people are talking about or a popular streamer with millions of followers tells everyone to buy it, it'll likely be -9%... -7%... -5%.... and weed down to a plateau as even really old games always seems to have a core group of gamers keeping it alive.
