This first person shooter game is perfect for you, if you want something that will give you hours or play time. The game now provides an introduction to the newer players, letting you play against people new people as well as giving you a guide on how to play. Firstly, there are multiple matchmaking options, a training mode, a store where you can buy all of the operators, weapons skins & camos, outfits and much more content. This can be purchased with the "Renown" (in-game currency) that you'll earn by playing the game, killing in different game modes as well as also winning, etc. The game modes are Hostage, Bomb and Secure Area, the most common being Bomb. In these modes you play as attackers for half of the game and defenders for the other half, these roles are very self explanatory.

There's also many different editions or versions of the game and I highly recommend taking any of the editions available, except the "Starter Edition". Why? Because the starter edition is just giving you access to a poor variety of operators on both the attacking and defending teams. The other editions will allow you to access more of the operators and for a cheaper in-game price. The better edition of the game = more expensive overall but has cheaper operators. The Deluxe edition is giving you access to the operators of the normal edition + the DLC's operators of the Year 1 Operator. The Gold edition will give you more operators, from the Year 1 Operator and the Year 4 Pass. And for the last edition, the Ultimate, you will get every single operator of every year. The Year 1, 2, 3 and Year 4 Pass.

When i originally purchased the game (a few days after release) There weren't any editions, just the bog standard game.... now after playing the game for 1.5k+ and doing some research into all of the different game versions we can see that:

The cost of four operators, compared:

Rainbow Six Siege Starter Edition: 50,000 renown (~60+ hours worth of gameplay)
Rainbow Six Siege Standard Edition: 5000 renown (~12 hours of gameplay)

Overall, I can say that in-game renown wise, you'll be getting between 100 renown and 300 renown per game, this depends on your kills, total points and if you win or not. At the end of the day its up to you what edition you go, take any edition you want. If you want the game to be harder and you want to grind to unlock everything get the starter or standard. If you want a little head start and a taste of what you can unlock but there is still plenty to learn and grind for, then get the Deluxe or the Gold edition of the game. If you want everything to already be available for you to use straight from the get-go then take the Ultimate edition. The Deluxe or the Gold edition of the game gives you the best overall idea of the game. It gives you a few operators, but not all. It allows you to pick between a few operators to let you understand the game and your play style. As well as also not being the cheapest or most expensive versions of the game.
