+
+Improve the run creation flow with better game filtering, box art display, and UX fixes.
+
+## Context
+
+The current run creation workflow has several pain points:
+- The game selection grid has no filters, making it hard to find games in a large list
+- Box art images exist in the data model but aren't being used — only the game color is shown
+- The "Next" button sits below the game grid, so users with many games may never scroll far enough to see it exists
+
+## Changes
+
+### Game Selection Filters
+- [ ] Add region filter (dropdown or pill tabs) to narrow games by region
+- [ ] Add filter for games with no active run (hide games that already have an in-progress run)
+- [ ] Add filter for games not yet completed (no completed run)
+- [ ] Consider additional filter criteria as needs emerge (generation, etc.)
+
+### Box Art Display
+- [ ] Use `boxArtUrl` as the primary visual for game cards in the selection grid
+- [ ] Fall back to the `color` field as background when no box art is available
+- [ ] Ensure box art looks good at card size (proper aspect ratio, object-fit)
+
+### UX Fixes
+- [ ] Move the "Next" / continue button to the top of the game selection step (sticky or above the grid)
+- [ ] Make it clear a game is selected before the user has to scroll
+- [ ] Consider showing the selected game summary near the top button
+
+## Files likely affected
+- `frontend/src/pages/NewRun.tsx` (or wherever the run creation wizard lives)
+- `frontend/src/components/GameCard.tsx`
+- `frontend/src/components/GameGrid.tsx`
+- Possibly new filter component(s)
