About Terra Firma

Terra Firma gives you the power to play god in a simulated world where the forces of nature interact in complex ways. Currently in early access, right now you can

  • Watch water flow through the landscape, eroding and depositing the land to form complex arrangements of tributary river systems, river deltas, lakes and oceans in an emergent fashion.
  • Observe the ecosystem respond to the availability of water. Plants automatically gross across the lanscape with different plants thriving in different environments depending on the distribution of water, nutrients and the geometry of the land.
  • Create your landscape using simulated plate tectonics, watching mountains form, grow and erode as millions of years pass in the blink of an eye. Customize the landscape to your will, raising, lowering and flattening it to see how the enviornment changes as a result
  • Zoom all the way from looking at an individual tree or plant to view the entire map across hundreds of square kilometres

I'm the very specific sort of turbonerd that can't get enough of real time erosion simulations. This one is pretty bare-bones, but it's free and clearly a tech demo for the sequel (which I will try if/when it gets out of early access) so I won't be harsh on it. I really like that it has support for multiple types of rock and for them to be in layers. Some way to get a cross-section view of your terrain would be a big help for tracking what's going on. Similarly, a transparency option for water to tell what's beneath the lakes.

there is a really annoying bug where lava and water doesnt add when zoomed in at maximum level with any size so i cant see how life reacts to the sudden appearance of lava. furthuremore when zoomed out to where i cant see the life does the lava suddenly appear. i do not recommend because i am hoping the devs see the negative reviews and fix the bugs. i will recommend afterwards

It's great for being free! It runs a bit slow at times but it's still impresive and fun to play around with. There isn't a lot of depth but as I said, it's free and fun so it doesn't matter to me. It's like a great demo for terra firma 2, because it made me hungry for more and I ended up bying it too. But if you don't have the money or don't care for more depth then this game is still great for what it is.

I love this game. First only plants spawned, but now also animals do, but I can't find any information about this update.

Games like Dying Light, where nightfall changes the rules

Games like Dying Light are easy to find if you only want parkour or only want zombies. These eight keep the part that matters: a city that becomes a different place after dark.

Games like Portal 2, where one idea carries the whole game

Games like Portal 2 all share one habit: teach a single impossible trick, then spend a campaign breaking it. From rewinding objects through time to Escher geometry that loops back on itself.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.

Toxic Commando Game Pass: subscribe, or buy the key?

The Toxic Commando Game Pass add landed on 12 November. Our price record since late September shows the key route barely moved, which changes what a subscription is worth.

Games like Titanfall 2, for the pilot or for the Titan

Titanfall 2's campaign changed its own rules every mission. Games like Titanfall 2 that keep one part of it — the wall-running, the mech, or a campaign that never settles.
