Balanced assessment (what’s good, what’s not)

• Generous for log-ins and grinders: catch-up friendly envelopes; free Tier VIII heavy on base BP track; Drops can award mid-tier premium vehicles.
• Time gating & fatigue: 50 stages in ~24 days is tight if you’re already mid-season; some veteran players call it “another extra BP chapter … cramming too many.”
• Monetization pressure: multiple weekly bundle waves and style sales might feel like a heavy store push during a milestone.
• Uneven bonuses regionally: APAC community code existed; EU/NA did not advertise an equivalent public code at time of writing.
• Community skepticism on “freebies” mix: some forum posts slam the rewards (e.g., “envelopes … nothing”), while others welcome a free T8 on base BP. This split is visible across community threads.

Key dates & schedules (high-level)

• Main celebration: Aug 8 → Sep 1, 2025.
• Official Anniversary streams: Aug 8 and Aug 12 (Drops enabled).
• Arcade Cabinet—Overwhelming Fire: Aug 15–18 and Aug 22–25 (weekend runs).
• Discount weekends & store waves: rolling through Aug 8–25 (discounts) and weekly offer waves across the event.
