Both "Rainbow Six Siege" and "The Division" share a number of identical aspects. Same genre, same multiplayer nature, and even the same publisher. Here's a quick comparison between the two to help would-be players and owners decide to get one or to just simply get them both.

Teamplay

Both of them heavily rely on their multiplayer aspects as they were designed mainly to be played with friends and other players all over the world. One significant difference between the two, however, is how much players will need to rely with other players.

"Rainbow Six Siege" relies greatly on teamplay and voice chat. That's what the "Rainbow Six" series had always been in this regard.

"The Division" differs to this greatly. Playing the game can be equally fun with friends or solo.

One more thing to look at it is "Rainbow Six Siege" could possibly be compared to games like "CS:GO" or something similar. "The Division" could be associated with games like "Destiny." Could somehow be associated with MMO sometimes, though no technically played as one.

Plot or Story

It is often a stereotype that multiplayer games like Tom Clancy's "The Division" and "Rainbow Six Siege" are thought to be without an actual plot.

Normally, with "Rainbow Six" games, no actual linear plots are set from start to finish. "Siege" is no exception to this, and "missions" are divided into "situations" only.

"The Division," on the other hand, has one main plot that players dive into. America is devastated by an outbreak and players are assigned by the president to contain the entire situation in various ways like saving civilians, fighting with hostile forces, etc.

Game Lifespan

With the factors discussed above, it would be clear that "Rainbow Six Siege" can be played on bursts and best enjoyed with friends.

"The Division," as it is often associated to being an MMO game, does have a couple of RPG elements on it. The game's got a loot/cover-based system, which may not be exactly present with "Rainbow Six Siege."

To sum it up, Tom Clancy's "The Division" is a game for both those who like to play solo or with friends. It has a number of interesting campaign missions and rich loot system. This game could be for those who loved "Destiny" and the likes.

Tom Clancy's "Rainbow Six Siege," on the other hand, is a game for those who like team-based gameplay and don't mind getting a narrative single player campaign. This missing element is exchanged with better strategic possibilities and competitive structure that strengthens its replayability.

Both of the games are well-received, despite being different at some points. However, if the budget allows it, getting the two is also worth it.
