Best expansions?

[Hauptj]

No offense to the game's creator, but I'm probably not going to buy all dozen expansions. Are there any that are considered must-have if you're going to play the game, or should I just pick a couple with characters that look kind of interesting?

[Jeysie]

If you want to pick between entire passes, Season 1 is probably the most useful pass.

Otherwise, yeah, it's kind of "what would you personally find interesting". A spin around the Sentinels Wiki[sentinelswiki.com] might help (please excuse that it's in the middle of a "remodel" layout-wise, so to speak).

Vengeance and Obliveon change the way the game play, so they are probably what bring the most to the game.

Villain of the multiverse is an expansion to the vengeance expansion.

Other expansion basically add more heroes, villains and environment deck to choose from

Mini-Pack 3, if you're looking for cheaper options for increasing replayability. Because of local Deadpool hero + insane villain + neat Environment.
I also picked Shattered Timelines on top of that, for Omnitron recursion. Contains no less insane villains against which extremely careful approach is needed.
Looking into getting Mini-Pack 2 for Miss Information villain which should be no less interesting!

OblivAeon is a kind of extremely high-level endgame content, as far as I know :)

Easy answer is Season Pass One, and then SP2, in terms of cost savings. But assuming individual expansions

Infernal Relics, Wrath of the Cosmos and Shattered Timelines are probably all about equal in terms of what they give you, two heroes and four villains. Rook City is similar but has a couple of heroes that are considered pretty bad, and some of the villains are on the frustrating side, so I'd rate it lower than the other three. I'd probably rate Relics-> Wrath-> Timelines in terms of giving you 'standard' fights if you want to keep it simple, but otherwise just pick whatever theme appeals to you.

Out of the mini packs, MP1 and MP both have solid villains that are on the easier side, so may be good as an early purchase. I'd probably avoid MP 2 and 3, as the villains are more 'puzzles' rather than straight up fights, again unless that's something you are after. MP5 is good for filling out your heroes, but has no villain.

Vengeance and Villains of the Multiverse change how the game works, so it's essentially a team vs team fight. I'd probably recommend this after playing the 'main' game if you want another way to play. Note that the villains aren't compatible between the two modes of play, but the heroes are.

Oblivaeon is kind of the equivalent of 'end game content' so I wouldn't really recommend it as an initial purchase.

Also worth mentioning that along with the new play mode, Vengeance offers two environments and five heroes, many of which are very good, while Villains only has four environments and more villains for the team mode. Which is important, but, y'know, if you're not dedicating a lot of time to playing team matches, it's far less useful overall.

Oblivaeon also has five very good heroes and some fun environments, the big guy can easily be ignored.

If you for some reason MUST only get a singular dlc and not a season pass (which is cheaper than buying stand alone heroes or any of the actual expansions or core game) shattered timelines is generally considered a beloved by the fanbase.
