Aliens vs. Predators Save Game Patch gives you an infinite number of saved games in Aliens vs. Predator

Gridlock is a collection of over 30 grid-based strategy games, including Ataxx, Reversi, Checkers, Gomoku, Connect Four, and more.
After launching the application, the game window will appear. Select the game you want to play from the "Game" popup menu in the upper right. Some games have different variations (board size, layout, etc); when one of those games are selected a "Variations" popup menu will appear from which you can select a variation.
The bottom right displays the color and status of the two players. Each players color is shown by a circle; the player whose turn it is has a filled circle. For games in which players have a score, the scores are shown next to the player labels. Popup windows underneath each players label allow you to specify whether each player is human or computer-controlled, and the difficulty of computer players. (Note that "Hard" and "Very Hard" computer opponents may take several seconds to make each move).
The rest of the window contains the game board. To make a move, click on the cell where you wish to place a piece. Some games require that you move from one cell to another; to do this first click on the cell you wish to move from, then click on the cell you wish to move to. (In some games such as Checkers you may be able to make a move containing several jumps; to do this click on each cell you wish to jump to in sequence). For all games, cells that are legal moves will become highlighted when you move the mouse over them. A black dot indicates the position of the last move. If you are unable to make a move, you can pass by clicking the "Pass" button on the right. The "Restart" button will restart the game, requiring confirmation if a game is in progress.
The "Preferences..." menu item in the main Gridlock menu opens the Preferences window, which allows you to change the appearance of the game pieces, and to enable or disable the animation when they are captured. Game pieces can either be bitmap images chosen from the popup menus, or solid colors chosen from the color wells.
Games can be saved and restored using the "Save" and "Open" commands in the Game menu. Games are saved with their full move history, so you can save a game after it is finished, open it later, and undo moves back to the beginning.
The Edit menu contains Undo and Redo commands. Selecting Undo will back the game up to the last time it was a human players turn. There is no limit to how many moves can be undone. Selecting Redo will redo a move that was previously undone, but only if no new moves were made after the undo.
The Window menu contains commands to toggle the display of network and statistics drawers. The network drawer is described below and is primarily used to chat with your opponent during a network game. The statistics drawer shows a table listing all the moves that have been made in the current game, and information on the analysis performed during the last move made by a computer player.
Enhancements:
- Added 6 new games.
- Built as universal binary for PowerPC and Intel processors. (Intel version is completely untested; if you have access to OS X for x86 let me know how it runs).
- Fixed display bugs when user interface scaling is active in Tiger.

Ophiuchus is a multiplayer space strategy game in a similar vein as the Master of Orion series.
It is a very early alpha release, and as such is currently very minimal but playable and networkable.
The game map is a rectangular board of tiles. A tile may contain a star. Each star is orbited by a single inhabitable planet. Each player starts out inhabiting a single planet, and owning 10 units of money.
Each planet a player owns adds 1 unit of money to their treasury per turn.
You may build spaceships at your colonies, which cost 4 units of money, and take 1 turn to construct. Spaceships move across the map at a rate of 1 square per turn. If a fleet encounters an uninhabited planet, it will automatically colonise the planet. If you encounter a planet owned by another player, you can attack and invade it.
Combat works on the simple principle of winner-takes-all. Whichever side has the larger fleet destroys the other side. You win the game by invading all colonies held by all other players.
Enhancements:
- When multiple players arrive at the same uncolonised system at the same time, none of them can colonise the planet. Previously, the player with the lowest ID got the planet, leading to an advantage to players with lower IDs. This was a problem especially in single player, where it gave a great advantage to the player over the computer.
- Attack commands now always give feedback.
