Hope this is in the correct area. Noticed there's been two 25% sales recently, do frontier do more sales like 50-75% like a lot of others on steam? Hate buying things then seeing it cheaper months later
During the summer and winter, Steam has a lot of good bargains going on.
If you check Steamdb stats for Planet Coaster, first price was from august 2016 and the first big discount 33% was june 2017
And in december 2017 they had the first 75% discount.
JWE has a more extensive discount history.
No guarantees ofcourse

But imo the most interesting months are June and December.
