Which one should I pick for a new project?

I can only answer questions about hearthsim/hearthstone-deck-tracker or lorisyounger/vpet.

If you're asking which of these two repositories to study or contribute to, I'd need more context about your goals. However, I can describe what each does:

• hearthsim/hearthstone-deck-tracker is a Windows desktop application (.NET/C#) that tracks Hearthstone card game decks during gameplay with an in-game overlay and deck manager.

• lorisyounger/vpet is a virtual pet desktop simulator (.NET/C#) with customizable animations and plugin support.

These are completely different projects—one is a game utility, the other is a pet simulation game. Your choice depends on what you want to build:

• Pick Hearthstone Deck Tracker if you're interested in game tooling, deck management, or Hearthstone automation.
• Pick VPet if you're interested in desktop simulation games or pet mechanics.

Architecture notes (from RepoPilot signals):

• Hearthstone Deck Tracker shows a C-grade architecture (50/100) with incomplete import graph analysis, no detected CVEs, but weak OpenSSF Scorecard (2.7/10).
• VPet's architecture signals are not analyzed, but it uses a plugin/MOD system [VPet-Simulator.Core/Graph/GraphCore.cs:L294-L346] for extensibility.

If you're starting fresh, clarify: Are you building a game utility, a game, or something else?
