What that means in practice

Warhammer 40,000: Space Marine II lands in the standard single-player range — a week or two of evenings for most players. Not a 100-hour sink, but enough to feel like a complete campaign.

Caveats

This is an average — some players blitz the main path, others pad the runtime with side content. Your mileage will vary by 30-50% either way.
Multiplayer and replayable systems (co-op, roguelike loops, endgame farming) push real-world time well past the single-player average.
Pre-release games don't have a tracked playtime yet; this figure reflects what's been logged in RAWG so far.
