Red Faction: Guerrilla always has been, and still is, the very best demolition game in existence. I know because I've looked far and wide, being a physics-obsessed gamer, but none even come close.
As a result, RFG has a remarkable replay value and a powerful, unique gaming experience. In no other game will you see buildings realistically collapse in such a thoroughly simulated and accurate manner. No other game will convey the sheer awe of toppling a giant structure or the sheer danger of standing too close. You will die when debris smacks you in the face, and it will be hilarious every time.
My only qualm with the game, and this is common critique, is poor firefights. Due to a simple flaw in the game's XML tables, much of the game was spent shooting baddies who refused to go down. This is easily solved, however:
I strongly suggest you check the latest mods after getting this game. You'll probably notice I'm a modder myself, so apologies if this seems like self-advertising, but the game missed much of its potential due to time constraints - constraints which I managed to circumvent by collaborating with other modders and taking my time throughout the years.
On top of that, the remaster is excellent. Forget lazy retexturing, this is a real remaster with substantial new features and graphics.
With this in mind, I cannot recommend RF:G RMT more. It deserves to be among the most popular games even today, in 2021.
