the current model is either pay the base-sub, or play in CPU limited mode. the only P2W interactions could be buying subscription tokens and selling them on the market for ingame credits (which you'd then use to buy more resources off the market from other players). You cannot purchase more compute time than the subscription allows

CPU-Wise, if you pay the compute time is tied to your account level, with a hard-cap if you're level 30 (there are still only a few players that have achieved this, it takes many months)
