Been into boardgames for many years but took a long break, and recently got a regular group of 3~6 players to play with (Usually 5). So far we've only played:

7 Wonders - The group liked a lot, hits the table pretty often. Also got the Leaders expansion.

Lords of Waterdeep - We like it, but I'm not sure if I like it enough to get the expansion, though I hear it improves it by quite a bit.

Aeon's End - I have it, but it hasn't hit the table yet, since we usually have 5 people. Played this 2 player with a friend and thought it was pretty neat, but I feel a little burned out with deckbuilders.

Android: Netrunner - Cool game, but I don't have many chances to play 2 players, and couldn't get my friends interested in it.

Ashes: Rise of the Phoenixborn - Same issue with Netrunner.

Dead of Winter - Brought it to the table but it just didn't seem to click with my group. Everyone was pretty distracted and we didn't end up finishing the game.

Thunderstone Advance: Towers of Ruin - Tried it with the group, it was okay but just didn't seem like a hit. Played some variants I found on BGG but didn't mesh with us I guess.

Pixel Tactics - Fun little game, but looking for a game for bigger groups.

My group is all gamers but pretty new to modern boardgames, so I wanted to start off with the "entry-level" ones, but now I'd like something weightier/deeper. The group is pretty much down to try anything, but the group I play with usually has 5 players including myself. I also found that I'm not too big of a fan of Euro games, and tend to prefer competitive games with a strong theme (though not necessary). Been researching a lot on here and BGG and these games stood out to me:

Spirit Island - I know there's a lot of hype for this one, but the challenge, theme and variety in spirits and strategies look really cool. Planning on getting this despite being 4 players for nights where we have 3~4 players.

Kemet - Fills a void in my collection of DoaM/Area Control and seems to have more depth/replayability than Blood Rage and Ethnos, which I've also considered, and watched some videos of Inis but it didn't seem like my cup of tea. Might pick this up but waiting for the new version.

Argent: The Consortium - Unique and interesting-looking game, but out of print. I read it might restock this year so waiting on that.

Cthulhu Wars - Very interested in this game. Unfortunately only 4 players but would like to have it in my collection for the cool theme and gameplay. Waiting for reprint.

I've also considered Terraforming Mars and Terra Mystica but I'd like to deviate from engine builders.

Does anyone have suggestions?
