Re: Make Perpetuum great again
For it's price, it's a good game to have on your account. It can easily became on top of the time on record. So in terms of games, it's a good choice.
But if you're looking for really best deals and don't mind to wait for them and save a couple of bucks, then for the Steam games in general:
1. It's a big benefit to buy games in "poor" regions. Permanent price reduction can be signifficant(~40%)
2. Buy on sales and check on http://steamsales.rhekua.com/, if the current discount is highest of all times, and if not, how frequent they are. Also, if discount rates are increasing on charts then maybe it's a good idea to wait for better deal. Most games start with small discounts on initial game or new DLCs, but never do more than 75% discounts. in perpetuum, discounts are the same, AFAIK. -75% on game and DLC on every seasonal sale.
