World of Diving is a diving simulator game that is currently available through Steam Early Access. In World of Diving you take to the water at a number of different locations ranging from a diving school (and the surrounding waters) to a sunken WWII ship. World of Diving has both multiplayer and singleplayer but due to the lack of players I've only experienced the singleplayer.
This game does include microtransactions but everything in the game's store can be purchased with in-game money (if you can be bothered to collect the stupid amounts necessary).
+Extremely relaxing to play
+A number of different dive tools to help you out
+Community challenges are well intergrated into each map
+A reasonable amount of maps at the moment
+There are some really cool cosmetic items in the shop if you like that kind of thing
+Wildlife is well designed and they seem to behave quite realistically
+Easy to use mission editor
+I haven't encountered a single bug or glitch
+/-Sea predators, such as sharks, pose no threat to you. It benefits how relaxing the game is but it does take away from the realism
+/-Apart from some pretty unimaginative challenges which have you take pictures of things there's not much to do which is fine if you just want to have a relaxing experience but makes the game get boring quite quickly
-Progress on this game is painfully slow, the devs do release weekly devblogs (which just show how little they get done each week) but it has been a very long time since the game actually got an update
-Itemshop prices (whether you're using real currency or in-game currency) are way too high
-Currently oxygen needs aren't in the game so you don't have to worry about your oxygen levels, takes away from the game's realism
-The game has a 'brony' level. Whether you are a fan of bronies or not this map really breaks the realism of the game as of course you wouldn't find such a thing in the real world
-The maps are very small and the wrecks within the maps also feel a bit too small
A nice diving game with great visuals that is let down by painfully slow updates and its lack of realism, I'd suggest buying this on sale and playing with friends.
