Short Discussion:
I've had good fun playing Stargate Timekeepers and it's certainly gotten better the more i played. From the start i was 50/50 on how much i'd enjoy it as I've never played stealth/tactic style games before. It holds a lot of nostalgic moments from the series, but all i can say is do a bit of research before purchasing the game, this style of game isn't for everyone, it's slower paced and requires a lot of patience.

Long Discussion:

Pros:
-I loved seeing literally anything from the show, like the F-302, Al'kesh, Tel'tak and even the mimetic device haha. You can also use a ZAT gun (which i recommend playing on story mode so you can use it accurately to the show with no Ammo cap).
-It caters to the fans well, it ties in with the end of Season 7.
-The story is pretty good, kinda plays homage to the episode Window of Opportunity
-The gameplay is fun, it was difficult for me at first but after practice its fine.
-The variety of unique abilities where good fun.
-The main menu being in the gate room looks awesome (very nostalgic)

Cons:
-The voice work feels off in many ways, it never feels like they're in the situation.
-No XP gaining or upgrades, i feel this game could've benefited highly with this.
-In some areas the controls seem a bit clunky.
-There are still quite a few bugs in missions and achievements not unlocking (This can still be fixed), but I've had to reload saves or replay a mission because it wouldn't go further.
-I would've loved to of heard more music sounding similar to the show (Bit of a nitpick)

Stargate is my all time favourite franchise and I've always said that Stargate video games has major potential across all genres as the series has incredibly rich lore. This still isn't the exact Stargate game I've always wanted to play personally, I think there is high potential for an open world FPS style game, this doesn't reach the epic scale that the shows does BUT i wouldn't criticise this game for that, this is a stealth/tactics commando style game and for what it is, i think it's entertaining and i would still recommend for any Stargate fan or fan of the game genre.
