I was going to pre order Stellaris, but I found out it's only 32 bit and still DirectX 9.0c. Big mistake by the devs. I will wait for a sale. One thing that annoys me is pre orders get exclusive races.
Paradox seems to love DLC. I certainly hope Stellaris isn't plague by $200 DLCs. I'm looking at Europa Universalis IV on Steam now for $39.99 and 41 of the DLC are $220.60! Total of $260.59 for a game. This must be the most expensive game with the most DLCs. And people complained about a Japanese/Chinese import game ROT3K 13 costing $89.99 on Steam.
All 32 bit games I've played suffers a big performance hit or crashes once it uses around 1.5 GB of memory. I believe Stellaris will be no different.
