The answer depends on **what you value in a shooter**. Here's a breakdown:
| Player Type | Verdict | Best Entry Point |
|---|---|---|
| Casual / Campaign only | Repetitive after 2–3 | MW2019, BO2, MW2 (2009) |
| Competitive MP (Ranked/CDL) | Deep, evolving meta | Current annual title |
| Zombies / Co-op fan | Varies wildly | BO3, MWZ, BO6 |
| Warzone / BR player | Separate ecosystem | Warzone 2.0 / MWZ |
| Completionist / Camo Grinder | Repetitive by design | Any — it's the loop |
