What is Nemesis? Nemesis is a theoretical brown dwarf star in orbit around our own sun, which may even have its own planetary system. Nemesis is also a 3D space shooter for the iPhone, iPad and Apple TV. (Want to try before you buy? Check out Nemesis Lite, also available in the app store.) The year is 3000... humanity has extended it's domain to the farthest reaches of the solar system. The new frontier is Nemesis, a star system rich with resources. Unfortunately, no one seems to agree on who owns this new frontier. Fight for your claim in this brave new world against ruthless enemies! Gameplay modes now include a campaign mode which can be played single-player or with a friend over wifi; and a death-match mode which can be played single-player or with up to 3 friends over wifi. VR headsets are now supported. While in VR mode, you can adjust: the screen size; vertical and horizontal position; the amount of parallax (that is, the space between your two virtual eyes); and whether or not your head movements are tracked. A VR headset and an external controller such as an extended gamepad are required. External controllers are also supported - both the standard profile (the one without thumbsticks) and the extended profile (the one with thumbsticks.) Our future is in your hands! Features: * Includes both a campaign mode and death-match mode, both of which can be played in single-player or multiplayer over wifi. * VR headset support. * Gamepad support (both the standard and extended profiles.) * Remote Control - control Nemesis 1.9 on tvOS or iOS via Nemesis 1.9 running on an iOS device. (Requires wifi.) * Beautiful graphics! * Intricately rendered explosion and smoke effects. * Nine unlockable ships and 10 unlockable environments. * Realistic physics. * Brutal AI. * 25 different power-ups, for all kinds of ways to smite your foes. * Listen to your own music while saving humanity. * Play in first person or third person modes. * Six different skill settings, from "practice" to "ace" in death-match; 5 skill settings in campaign. * User settable kill-limit in death-match mode. * Multi-player over wifi.

Rocket Simulator allows you to launch a rocket into space and view various objects currently in Earth orbit. Currently you have the option of launching 4 rocket models and visit 6 objects in space, such as the Hubble Telescope, International Space Station and Kepler. I originally wrote this game for my 19 month old son to teach him about rockets & space flight. He was easily able to learn how to launch a rocket and control the camera within a few minutes. Although the controls are extremely simple even for a kid, adults that like rockets & space explorations will find plenty of enjoyment in this simple yet fun space simulator.

Verdict

The call

The clearest difference is review sentiment: Nemesis at 80% against Rocket Simulator's 21%. Nemesis also leads on rating (4.0 vs 2.5) and update cadence (every 3 months vs every 7 months). Rocket Simulator's advantage is price (Free vs $1.99) and ratings volume (179 vs 2). On ads, in-app purchases and device support there is nothing between them.
