The Expanse: Osiris Reborn trailer just dropped at Xbox Partner Preview. Reddit is hyped, calling it the Mass Effect successor we've been waiting for. Let's dive in.

Space RPG fans, wake the f*** up! The Xbox Partner Preview just dropped a massive bomb called The Expanse: Osiris Reborn. If you've been starving for a true sci-fi RPG and missing the golden days of Mass Effect, it’s time to get your hype thrusters ready.
Slated for an early 2027 release (yeah, a 2026 preview for a 2027 game, classic gaming industry pacing), this title is being crafted by Owlcat Games. These are the devs known for insanely deep narratives and brain-melting dialogue trees.
The trailer gave us everything we wanted: dark sci-fi vibes, branching narratives, and a quote that hit right in the feels: "The universe never tells us if we did right or wrong." That’s basically looking directly into the soul of the old Mass Effect morality system. However, keeping it real here... the gunplay looked a bit janky. The animations felt stiff, kinda like watching someone play an FPS on a 200ms ping.
Scrolling through the thread, the community is basically split into a few main camps:
1. The Hype Train: "The Mass Effect successor!" Top comments are already crowning it the spiritual successor to Mass Effect. Fans of the books and TV show (like Zakazi) are absolutely losing their minds.
2. The 2027 Showdown Eagle-eyed gamers pointed out that both this game and Exodus are targeting an early 2027 launch. The sci-fi RPG genre has been pretty dry lately (Starfield was okay-ish, and Outer Worlds is getting old), so having two heavyweights dropping simultaneously is going to be a bloodbath for sales but an absolute win for us gamers.
3. Forgiving the Jank for the Lore Some tryhards noticed the stiff shooting mechanics right away. But honestly? The general consensus is that Owlcat’s top-tier storytelling (shoutout to Rogue Trader) completely overshadows some clunky animations. People are basically saying: "Give us God-tier writing, and we'll forgive the janky gunplay."
From a dev perspective, building a massive space RPG with branching dialogue is an absolute nightmare for resource management. I'd much rather take stiff gunplay with a bug-free, elite narrative over a gorgeous AAA game that drops to 15 FPS on launch day and requires 10 hotfixes just to run without crashing.
The lesson here for game studios? Lean into your strengths. Owlcat knows they carry the game with their writing, not their shooting mechanics.
Bottom line for gamers: Add it to your Steam wishlist, but remember the golden rule of gaming—DO NOT PRE-ORDER. Wait for the Day 1 reviews, let the whales test the bugs for us, and then decide if it's worth your hard-earned cash.
