With the addition of the Nemesis system, Shadow of Mordor becomes something truly special, giving the player a more dynamic experience, which allows us to have our own unique adventures, with enemies we'll make a personal history with.
If you enjoy twin-stick shooters like Geometry Wars, then maybe you can give this a try. It's definitely a competent game for the genre and will scratch that itch, if you've got it. For me though, the whole time I was playing I just kept thinking about how much better Geometry Wars was, and that I'd rather be playing an HD release of that instead.
With that said, nineteen years later Worms is still a fun game overall, if it is a series that appeals to you. It's one of the best examples of "more of the same", as it really is the same game as everyone before it. If you enjoy the series, and like having new versions, with new maps, weapons and prettier graphics, then go nuts, there's nothing to not like here.
If you enjoyed the other games, this is likely more of the same, but in a different setting and probably a bit prettier. However, if you're new to the series, like me, and curious to give it a go, you might be better trialing it out with one of the earlier, and cheaper, games in the series first.
If you are into space combat action (and that's all you are looking for) then Strike Suit Zero: Director's Cut might just scratch that itch for you. It's not a bad game and the general combat can have moments of fun. But as I said at the start, most of the time when I was playing this title, I just kept thinking to myself "I am not enjoying this and would rather be doing something else right now". Take that for what you will.
I've really enjoyed coming back to Diablo 3 with this expansion, Reaper of Souls. I had grown bored of playing through the same stuff, so having some fresh content to dive into has been great. It's still the same, fun game it always has been, but now with more stuff to do after you finish the story, and extra randomness that can hopefully stop its end game from becoming stale as quickly as the main game did. Whether or not this new Adventure Mode will be enough to keep away the boredom of repetition is something that is too early to tell. But after putting a good chunk of hours into it, I am hopeful it will.
