Soon to be removed games: Polykat and Infinite Air with Mark McMorris both 90% off

Sometimes a marketing step or the final way, to generate purchases for trash. Works sometimes good in the past, to generate profit.Then they don't removed it.
Other removed it, or they bring it again as "Remaster"

Desperate move to sell a few copies to collectors.

Some because of licensed stuff in the game/the game itself expire

As far as larger IPs, it's almost always due to licensing issues.

For games without an offline mode, it's often due to expense related to server hosting.

For low-end games, it's usually a response to criticism or a form of exploitation to try and persuade bulk sales. For either, there's always a risk that they'll go into junk bundles before vanishing, as well, making the collector gamble all the more wasted.

Oh, thanks for mentioning it. I want that game. Gotta find the best deal for that.

That will make a really long subject title but thanks.

What's up with the absolute douchebags giving "Infinite Air" negative reviews for requiring a controller? It had mostly positive reviews before it went in a bundle recently. (People got it for next to nothing to begin with) I checked that game because I was thinking about getting the bundle it was in. Therefore, there's nothing wrong with the game itself. It's just that it requires a note on it's steam page to say that it requires a controller to play. I've seen several games with that note.

Wonder if the mass influx of negative reviews has anything to do with their decision to cut their losses and run. If so, that's sad.

honestly, probably no

Steep is much more enjoyable compared to the MacMorris game

now this one is probably up to individual rig but Infinite Air had some ridiculous lag on my system which, while not a power, had less issues running Steep

Short answer: no

Long answer: Infinite Air has great snowboarding physics and score is based on how clean your tricks are and not how crazy they are.
The levels and objectives of the carrier mode are decent but sometimes, it's not clear what you actually have to do.
The big problem with Infinite Air is how badly it runs. It's a Unity game (so unoptimized) and it will make your rig run supper hot.
I was bored after 13 hours where I'm still enjoying Steep very much after 70+.
You can read my review on BLAEO but what I wrote about is pretty much the same.

It's an alternative to Steep.
Other gameplay, both are cool.
I prefer STEEP, but Infinite Air is pretty cool as well.
And when you like these or SSX like, then buy both.
And 2.99 are not much.
If you spent less, then buy it on DIG for 0.90$ :)

I have both, played Infinite a little then played Steep later and I think you will be fine with only Steep.

Infinite air is pretty decent actually. I was looking for a nice snowboard sim and also found out about The Snowboard Game which is probably the better one, if you can handle the learning curve. Infinite Air feels less arcady than Steep, but also less complete, still fun to be had.

no

Indeed, can't believe Polykat was $15 to begin with
