Compare the OMORI and UNDERTALE collector's editions on box contents, platform options, and price so you can pick the indie game collector box that fits your shelf.
Quick answer
Choose the OMORI Collector's Edition if you want a display-ready box built around a playable piano music box and OMOCAT-illustrated sheet music. Choose the UNDERTALE Collector's Edition for PC if you want the complete soundtrack on two CDs and a sheet music booklet with Toby Fox's annotations.
What each collector's box is actually built around
These are not the same kind of collector's edition. The OMORI box is organized around one centerpiece: a piano music box that plays "Duet," paired with a sheet music booklet wrapped in original OMOCAT illustrations. The UNDERTALE box is organized around the music as a listenable archive: the complete soundtrack spans over 100 songs on 2 CDs, and the sheet music booklet covers six songs with annotations by Toby Fox.
That difference matters more than the number of extras. If you display your collector's editions open, the OMORI music box gives you something to show. If you actually listen to game music away from your desk, the UNDERTALE CDs are the more practical inclusion.
Platform and format limits to check first
The OMORI Collector's Edition lists Platform as its available option type, so the version you pick is part of the purchase decision. The UNDERTALE Collector's Edition is listed for PC, with physical copies available now and a special collector's edition sold exclusively on Fangamer. Neither listing supplies details beyond those option types, so confirm the exact platform or style you need before ordering rather than assuming a version exists.
Price and catalog comparison prices
At the time of writing, the OMORI Collector's Edition is listed at USD 52.92 against a catalog comparison price of USD 84.00. The UNDERTALE Collector's Edition for PC is listed at USD 47.36 against a catalog comparison price of USD 74.00. Both show a gap between the current price and the comparison price, but treat that gap as catalog context rather than a permanent discount promise.
Trade-offs to weigh before you choose
- Display vs. listening: The OMORI box centers on a piano music box and display box, while the UNDERTALE box centers on a two-CD soundtrack. Pick the one whose main extra you will actually use. Decide whether your shelf or your stereo gets the bigger payoff.
- Platform commitment: OMORI lists Platform as an option type, so the platform you choose is part of the order. UNDERTALE is listed for PC. Check that the version matches the device you own before buying.
- Sheet music depth: OMORI includes a sheet music booklet for "Duet" with OMOCAT illustrations; UNDERTALE includes six songs with Toby Fox annotations. Choose based on whether you want one illustrated centerpiece or a broader annotated set.
- Price gap: OMORI is listed at USD 52.92 (catalog comparison price USD 84.00); UNDERTALE is listed at USD 47.36 (catalog comparison price USD 74.00). Compare the current prices, not the comparison prices, when budgeting. The lower current price belongs to UNDERTALE, but the contents differ enough that price alone should not decide it.
