Thanks — this one pushed me to make a real improvement, so I appreciate it. Two parts:
On choice: there's actually a full catalog already — 8 CPUs, 8 GPUs, plus several motherboards, RAM kits, PSUs and cases across Budget → Mid → Pro tiers, each with genuine tradeoffs (matching socket, RAM type, PSU wattage, case airflow, durability). What makes it feel like one option at the very start is your budget — early on you can only afford the budget tier, and the tutorial points you at a cheap first build. As you earn money the mid/pro tiers open up and the choices get interesting. So there are plenty of viable builds; they're gated by cash, not locked away.
On clarity — you were 100% right, and it's now fixed. Instead of a vague "RAM type mismatch," the builder now spells out exactly why, e.g. "RAM mismatch: this board takes DDR5, but you picked DDR4 RAM," or "PSU too weak: this build draws ~480W but the PSU only supplies 350W." Live in the next update. Thanks for the sharp feedback! 🖥️
