## Analyst notes (AI-assisted)

Shieldwall is a tactical squad-level RTS hybrid where players build and command Roman armies to capture objectives in campaign and multiplayer skirmishes.

Shieldwall has achieved solid lifetime performance (1M+ net revenue, 226k units) and maintains steady positive sentiment (86%) with a core audience returning regularly despite 17+ months of dev silence. The title is a quiet earner generating 10k/mo mid-range residual revenue, but reviews universally flag a single design flaw: punitive AI and difficulty curve that blocks progression and kills retention. A light acquisition for balance iteration and mod-support addition could unlock the 2+ year stalled opportunity_usd signal (13.5k/mo potential); alternatively, publish a free-to-play reboot or license the IP to a larger tactical-game publisher.

- Most realistic play: acquisition
- Risk (tech): No workshop/mod support limits long-tail engagement; players explicitly cite this as the reason they churn after campaign completion.
- Risk (market): Studio status is fading (2 titles, no dev post in 17 months); acquisition of the code alone risks orphaning the title unless buyer commits to post-launch design patches.
- Risk (other): Campaign difficulty is a retention cliff: multiple reviewers describe AI as unfair (unlimited economy, siege engines with 'homing' accuracy, spawn camping), making the game feel broken rather than challenging.

What players are asking for:
- Steam Workshop/mod support to extend replayability beyond campaign
- Campaign difficulty rebalance and AI economy tuning to reduce player frustration at mid-game (level 8, Alesia, siege maps)
- Additional maps, unit types, era variants, and QoL customization in multiplayer (flag spawning rules, team-count flexibility)
- Better tutorial or UI clarity so players do not feel forced to YouTube strategies to progress

Suggested first moves:
1. Audit campaign balance data (win rates, replay counts per level, dropoff funnel) to identify exact difficulty cliff points; patch AI economy and siege-weapon tuning as a low-cost, high-impact fix to reduce churn.
2. Scope a Steam Workshop implementation or commissioned mod framework (cosmetics, maps, unit skins) to prove retention uplift before major reinvestment.
3. Consider free-to-play conversion with a $5-10 cosmetic/season pass layer to re-engage lapsed players and lower price-sensitivity friction cited in reviews.

## Methodology

Units are estimated from Steam-purchase reviews times a release-cohort multiplier (Boxleiter method, 20-75x by year). Revenue uses an effective price (lifetime discounts and regional pricing) and nets out VAT (~13%), refunds (~9.5%) and Steam's 30% cut: roughly 55% of gross reaches the developer.
