Buy BIOTOPE Aquarium Simulator Steam Key

Q: Why is the Steam Key of BIOTOPE Aquarium Simulator safer than the account format?

The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download BIOTOPE Aquarium Simulator to your game library. The account format requires more complicated steps and is more prone to errors during activation.

Is it worth buying the Steam Key for BIOTOPE Aquarium Simulator now or waiting?

That €1.55 key is at one of its best prices.

Those €1.55 are 78% below what it usually costs, measured on the store price.
8 stores sell the Steam Key at the same time, and with that much competition the price moves almost daily.
Not counting today, only 103 days out of the 1,860 days on record were this cheap or cheaper; the lowest it has ever cost is €1.17.

At this price it is worth buying the Steam Key now: what you stand to gain by waiting is a few euros, and it is not guaranteed.

Worked out from 2,571 daily records of the Steam Key for BIOTOPE Aquarium Simulator across 14 stores. See the full price history.

The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.

Which BIOTOPE Aquarium Simulator format should you buy?

By format: Steam Key from €1.55 and Steam Gift from €1.78.

Can you activate BIOTOPE Aquarium Simulator in US?

8 of the 10 offers work on US — the Global ones plus the ones issued for your own region.

Why is there such an expensive BIOTOPE Aquarium Simulator offer?

One listing is worth ignoring: the Steam key that Fanatical has at €15.96 is more than 10 times the cheapest offer and is not what this game costs. The number to work from is €1.55 at Greenmangaming.

This version of Biotope is a cd key, also known as digital format, and is cheaper than other versions. From Gocdkeys we group both official (Steam) and unofficial (G2A, Instantgaming, Kinguin,...) stores that sell the Biotope key to offer a price comparison to our users.

We can buy Biotope from the STEAM shop at a price of 22.49€ which will automatically add the game to our "Games Library" and we can start with the download.

Or we can buy Biotope in other online stores such as G2A, InstantGaming or Kinguin, among many others, at a cheaper price than the official STEAM store. These "Unofficial" stores sell activation codes, known as cd keys or STEAM Keys (although it may also be available in STEAM Gift version). The activation of these digital codes is completely legal and does not pose any risk to users.

BIOTOPE Aquarium Simulator is the first and only photorealistic aquarium simulator in which we can create fish and plant populations and actively influence their life cycle in an unimaginable way. Although it may seem simple, managing an aquarium is more complex than we think. We will face numerous strategic challenges and will have to manage the expansion and operation of the aquarium, with a limited budget. Cultivate, breed and market fish and plants.
